Complexation investigation

The complex investigation of the heart of IHD patients with Myocardial Infarction (MI) was performed. The results obtained showed that all investigated elements divided in two groups - the behavior in different parts of the heart of the certain elements (e.g., Se-Rb) were synergetic, the behaviour of another one was antagonistic (e.g., K-Ca, Fe-Br). 

An evaluation of the HVAC system may include limited measurements of temperature, humidity, air flow, as well as smoke tube observations. Complex investigations may require more extensive or sophisticated measurements of the same variables (e.g., repeated COj measurements taken at the same location under different operating conditions, continuous temperature and relative humidity measurements recorded with a data logger). 

It was therefore with some confidence in the infra-red and Raman spectroscopic methods that a much more complex investigation was carried out on the molecular orientation in one-way drawn PET films which show uniplanar axial orientation 5). In such films the condition of fibre symmetry is removed in two ways (1). There is no longer uniaxial symmetry of the distribution of chain axes. 

Complex investigations, for example on the (sub)cellular level, can be performed in a fraction of the time required for wet [in vivo or in vitro) studies. 

Our group has continued to examine several other rare Rg- XY systems, and a list of the experimental and theoretical T-shaped and linear binding energies of these complexes is presented in Table 1 [52-55,57]. The general features and characteristics of the spectra for all of the complexes investigated are similar to those observed in the spectra for the He ICl and He Br2 systems. The linear features are observed to higher transition energies than the T-shaped features. In contrast to the rather simple rotational structure of the T-shaped features, the linear features possess much broader and structured... 

Methods and scripts are software resources that help the operator to set up complex investigations without concentrating on the basic requirements. Furthermore, these software modules can handle the interaction between various parts of the NMR software package, to support the geometry editor, auto adjustments, routine parameter handling or pulse handling program. 

All borabenzene-metal complexes investigated structurally so far show very similar patterns for the ligand geometry (Table I) and for the metal-ligand bonding (Table II) only the cobalt complex 6 deserves separate consideration (see below).

Dimeric Cr(II) and Mo(II) carboxylate complexes, investigated by Green et al (119,120) show low-energy multiple ionization patterns of the [d4]2 system, assigned to metal-metal a, n and 8 bonding and antibonding orbitals. 

In a first apphcation of general interest, fluorenyllithium complexes (1, Scheme 1) were studied by solid state NMR spectroscopy. One reason for the choice of this system was that the results from the X-ray investigation presented at that time and solution NMR investigations were in conflict. The bis-quinuchdine complexes investigated in the solid state by X-ray analysis show that the lithium cation is asymmetrically positioned relative to the carbon framework of the anion, mainly interacting in a fashion with carbons C-1, C-9a and C-9 (Figure 9) . 

When cr0 is plotted vs. AE, a linear relationship is obtained (Figure 3). Poly-acenes show a similar linear relationship, which may be parallel to that of the isonitrile complexes investigated and which is displaced toward lower values of o-o- A comparison between the isonitrile complexes and polyacenes demonstrates most clearly the wide ranges of activation energies, AE, and of the constant, o-o, which may be achieved merely in one series of coordination complexes as compared to polyacenes. 

This transformation is in contrast to the corresponding more sterically crowded [Mo N (Bu )Ar 3] which does not exhibit this type of behaviour. Initially it was assumed that the cyclometallated structure would inhibit the type of reactions (e.g. with N2 or N2O) shown by the t-Bu substituted tris-amido complex. Investigation of the chemistry, however, showed that this is not the case and the imine-hydrido product behaves as an effective source of [Mo N(Pr )Ar 3] which, because of its less sterically encumbered nature, exhibits reactivity not observed for its more hindered [Mo N(Bu )Ar 3] counterpart. A simple example is provided by complex formation with benzophenone to give [Mo N(Pr )Ar 3(r 2-OCPh2)], whereas the Bu analogue did not react with this reagent. ... 

For a same molecular ratio of aqueous NaY solutions (Y = OH, Cl), experimental data underlines specific effects of nascent OH radicals on transient UV and near-IR electronic configurations. Complex investigations of PHET reactions in the polarization CTTS well of aqueous CT and OH ions are in progress. We should wonder whether a change in the size of ionic radius (OH -1.76 A vs Cl" 2.35 A) or in the separation of the energy levels influence early branchings of ultrafast electronic trajectories. A key point of these studies is that the spectroscopic predictions of computed model-dependent analysis are compared to a direct identification of transient spectral bands, using a cooled Optical Multichannel Analyzer... 

The fibrillar structure of crystalline polymers is determined by molecular characteristics, the initial morphology and orientation conditions. Recently, a complex investigation of the effect of molecular parameters (MW, MWD and degree of branching) and orientation parameters (temperature and draw ratio) on the morphology of PE and its thermomechanical behaviour has been reported 181 185). 

If the properties of the various dinuclear complexes investigated appear to be very sensitive to both factors, we can nevertheless discriminate them roughly (and in a somewhat artificial way) by discussing the data obtained for the family of methylene-bridged knots and related unknotted complexes and, separately, those obtained for the phenylene-bridged knots. 

The spin-equilibrium dynamics of iron(III) complexes in solution have been examined with the techniques of Raman laser temperature-jump, ultrasonic relaxation, and photoperturbation. The complexes investigated, the relaxation times observed, and one of the derived rate constants are presented in Table IV. Many of the relaxation times are quite short, and some of the original temperature-jump results (45) were found to be inconsistent with more accurate ultrasonic experiments (20) and later photoperturbation experiments (102). It has not been possible to repeat some of these laser temperature-jump observations. Instead, the expected absorbance changes and isosbestic points were found to occur within the heating rise time of the laser pulse, consistent with the ultrasonic and photoperturbation experiments (20). Consequently, none of the original Raman laser temperature-jump results is included in Table IV. 

The present investigation was suggested by Prof. N. Semenov who also proposed the chain mechanism of the process. Our paper represents part of a large complex investigation carried out at the Institute of Chemical Physics in which took part G. Barskix, N. Chirkov, D. Frank-Kamenetskii, A. Kovalskii, A. Nalbandian and P. Sadovnikov. 

The TCNE adducts of a variety of other [nq4-Fe(CO)3]- complexed trienes and tetraenes have been investigated. In most cases the adducts have been oxidatively cleaved from the metal with CeIV and the free ligands recovered in good yields. Reactivity patterns generally follow those described above for cy-cloheptatriene and cyclooctatetraene complexes. Specific complexes investigated include [Fe(2,4,6-cy-clooctatrieneone)(CO)3],61 [Fe(tropone)(CO)3],62,63 [Fe(heptafulvalene)(CO)3] and various 8-substituted... 

The first metal(salen) complex investigated as an asymmetric phase-transfer catalyst was methionine-derived sulfonium salt 29. It was anticipated that the sulfonium salt... 

The first piece of pertinent information is that for several Cr(NH3)5X2+ complexes the stereochemistry of the product is cis-Cr(NH3 )4 XY2+ where Y is the entering group. Some of the complexes investigated and their photosubstitution products are given in Table 3.19,22 28) jf we take these results at face value it is clear that Y does not occupy the binding site occupied by the leaving NH3 group. 

Another example for mono-chelate complexes investigated for their antitumour activity857 consists of tetraethylammonium halide adducts 485 (X = Hal, R = Aik, Ar) containing 0,N,0-tridentate dianionic ligand. 

The systems involved in the defense mechanism of the body are both varied and complex. Investigating the role of biologically active peptides has proved to be a very promising line of research. The main focus is on two peptide groups, namely on immunomodulatory (stimulating the immune response) and antimicrobial (inhibiting pathogenic microbes) peptides.
