The experimental results and discussion

THE EXPERIMENTAL RESULTS AND DISCUSSION 2.1. JT complex in a site of cubic (trigonal) symmetry 

The changes of the X-band spectrum over the temperature range 4-120 K at the stationary magnetic field HII (1 0 0) (C4) axes are shown in Fig. 1. The parameters of the spin Hamiltonian describing the spectrum are provided in Table 1. 

Such behavior of the spectrum fully corresponds to the predictions of the theories of motional narrowing of Anderson, Kubo and Tomita and others [10,11]. With temperature increase the transition rate between different JT conformations 

The temperature interval in which the spectrum vanishes is large enough to increase the population of the necessary vibronic level and of in order to switch from the condition of slow motion to those of fast motion without taking into consideration excited vibronic levels of higher energy. 

In the present case any deformations of the JT complex position due to external strain are random and close to zero. We take into account the directed ones by the addition of deforming components of tetragonal, Ae, or rhombic, Ae, symmetry, or their combination, to the vibronic Hamiltonian. Now we move to the situation of the slightly elongated host octahedron, i.e., to the case Ae 0 Ae 2/3.

The experimental results and discussions presented by the various authors cited above, in combination with the unified mechanism proposed by van der Meerakker and described in Sec. 3, make it possible to write the following reaction equations to formulate the mechanism of the partial anodic process ... 

The adsorption isotherm of xenon on graphite has been measured at different temperatures [56-60]. Review the experimental results and discuss the surface phases of xenon that were detected. Would you expect krypton to behave similarly on the same substrate Explain.

From the experimental results and discussions presented in section Impact of Gas/Liquid Ratio on SE Structure, it became obvious that GLR and the gas-Uquid interaction pattern (internal and external mixing nozzle) have specific impacts on the resulting emulsion microstructure. The influence can be so significant that the microstructure of any multiple emulsions can be destroyed during spray processing without considering these issues. 

The majority of researchers, however, are inclined to believe that the tantalum reduction process takes place in a single step. Experimental results and discussions confirm that tantalum is reduced from fluoride, fluoride-chloride and oxyfluoride melts containing K2TaF7, via a single stage in which five electrons are transfered [546 - 548] ... 

The subsequent chapters will describe various quantum-chemical methods, compare them to experimental results and discuss their applications to such biological systems as amino acids, peptides, carcinostatic drugs, and DNA fragments. Proteins and large DNA fragments cannot be treated as yet with quantum-chemical methods, due to their size, but progress is being made continuously. 

On the basis of these experimental results and discussion, we tried to establish a convenient and useful method for quantitative evaluation of the molecular orientation in thin LB films using FT-IR transmission and RA spectra. Here, we assume a uniaxial orientation of the transition moment with an angle < > around the normal axis, Z, to the LB film surface i. e. the XY plane (Figure 8). In this case, the ratio of the absorbance of a particular band in the transmission spectrum, AT, to that of the same band in the RA spectrum, AR, is given by... 

Because oxygen is probably the most extensively studied molecule in both experimental and theoretical investigations of low-energy electron attachment, the experimental results and detailed discussion are presented in this paper particularly for O2. The only accepted mechanism has been the overall two-step three-body mechanism, which was originally suggested by Bloch and Bradbury [79] (referred to below as BB ) and was later modified by Herzenberg [80] to make it consistent with modern experimental data. The BB mechanism for O2-M mixture, where M is a molecule other than O2, is expressed as follows ... 

In the following discussion of some earlier work in the field of adsorption in the light of the experimental results and concepts in this article, we shall attempt to evaluate how much of the results can still be relied upon and what results should be reexamined with modern tools and techniques. 

We would like to thank Dr. O. J. Eder for sending us the experimental results and Prof. S. H. Chen for helpful discussions. This work was supported by Project SQUID of the U.S. Office of Naval Research, the National Science Foundation, and Army Research Office, Durham. We are also grateful to V. F. Sears and B. Berne for calling to our attention an incorrect statement in the original manuscript. 

The study of several polyelectrolytes through various experimental methods has led to diverging results and controversial conclusions. This situation has recently been summarized from the theoretical point of view in [28,95-97]. However, there are some interesting data resulting from experiments with PDADMAC and DADMAC copolymers which remain unexplained. The aim of this Section is to present these experimental results and, furthermore, to discuss the data in terms of existing polyelectrolyte theories. For a better understanding of the experimental results under discussion a short fundamental summary of the main properties and parameters shall be given. However, it is not the aim of this review to evaluate the various theoretical approaches.

A number of studies have been performed in the context of a theory that proteins and polynucleotides were formal in a suspension of proteinoid microspheres and the microspheres could then have evolved to contemporary cells. The experimental results and evolutionary considerations have been summarized in the textbook of Fox and Dose published in 1977 2). This review therefore deals with studies since 1977, although some description of literature before 1977 is reviewed as occasion demands. Since the evolutionary consideration of proteinoids and proteinoid micro-spheres has been discussed in much literature and many books, (e.g. 2, 3), the attention in this paper is focussed on the description of the biochemical and experimental parts of the literature. Inasmuch as protobiological activities of proteinoids in solution are carried into microspheres 2), experiments with proteinoids in solution are not excluded.

Despite the experimental results and theoretical calculations reported so far, a conclusive description of the ligand packing for homoligand nanoparticles cannot be drawn. The present idea is that the real structure of the ligand shell results from the interplay between van der Waals interactions and the tendency of the thiolates to reach the optimal tilt angle on each facet, as discussed by Stellacci and coworkers on the basis of STM analyses.214,215...

As already discussed, for the partial blocking of ZSM-5 by benzene, the experimental data discussed herein will be compared with two cases of an obstacle distribution (1) in the connecting pore segments or (2) in the channel intersections. Figure 33 compares the experimental results and the computer simulations. For pyridine, the self-diffusion data are in satisfactory agreement with the model for obstacles distributed over the channel intersections. One has to conclude, therefore, that the chemisorbed pyridine molecules and, thus, the Brpnsted acid sites, are localized near or even in the channel intersections. That is to say, all catalytically active centers are accessible for a reactant molecule in a channel intersection. 

In the present paper we report about experimental results and discuss the revealed regulations of carbon adsorbents synthesis. The width of pores in adsorbents as a function of cartwnization tenqreratuies is found to be of extreme character. We suggest a working hypothesis erqrlaining the pore width depetulence. However, we need more experimental results to confimi our hypothesis. 

In this section we report our experimental findings relatively to three different reactions of CN radicals with simple alkynes, namely acetylene, methyl-acetylene and dimethyl-acetylene. We have selected these reactive systems for different reasons the reactions with C2H2 is the prototype for the class of reactions CN +- alkynes/polyynes, thus is expected to reveal key concepts for reactions with the higher members of the same series the reactions with methylacetylene and dimethylacetylene were selected to observe the effect of the H substitution with one or two alkyl groups. In all cases, the experimental results are discussed in the light of the ab initio electronic structure calculations for the stationary points of the relevant potential energy surfaces. 

In the tutorial, a scientific paper is deconstructed into its components (Introduction, Experimental, Results and Discussion, Conclusions, References and Abstract). Each component is examined and decoded to identify the key elements and features that are typically included. Eor example, when writing an Introduction to a scientific paper, we recommend the students address the following questions (1) What has been done before (2) Why are we doing this experiment (3) What are we going to do (4) How are we going to do it ...
