CROSSED MOLECULAR BEAM REACTIVE SCATTERING TOWARDS UNIVERSAL PRODUCT DETECTION BY SOFT ELECTRON-IMPACT IONIZATION... 

In this chapter we have discussed the successful implementation in our laboratory, for the first time, of the soft (i.e. low energy) electron-impact ionization method for product detection in crossed molecular beams reactive scattering experiments with mass spectrometric detection. Analogous to the approach of soft photoionization by tunable VUV synchrotron radiation,...

Conventional molecular beam reactive scattering studies have excelled in the determination of the angular and velocity distributions of reaction products, but direct information on the internal state distributions has been sparse. One of the most important of the non-beam methods for learning about the partitioning of reaction energy into the internal degrees of freedom of the products has been infra-red chemiluminescence studies. Unfortunately, this technique has hitherto been limited to hydride compounds, principally hydrogen halides. We present an alternative technique based on electronic fluorescence spectroscopy.

Crossed molecular beam reactive scattering facilitates experimental determination of the angular and velocity distributions of chemical products from elementary bimolecular reactions. The technique involves production of two molecular beams containing the reactants, initially moving at right angles relative to one another, in an evacuated...

MOLECULAR BEAM REACTIVE SCATTERING OF Br FROM Pd(lll) USING AN ELECTROCHEMICAL EFFUSIVE SOURCE... 

The present paper seeks to clarify these aspects of the Pd-Br2 system by a modulated molecular beam reactive scattering investigation of the surface reaction kinetics. The object is to identify the kinetic order of all overlayer evaporation pathways and to obtain values for all rate parameters which characterise them. 

Molecular Beam Reactive Scattering of Br2 from Pd(lll) Using an Electrochemical Effusive Source... 

Characterization and analysis are performed using the following surface science techniques temperature programmed desorption/reaction (TPD/TPR), pulsed molecular beam reactive scattering (pMBRS) (IRRAS), metastable impact electron spectroscopy (MIES), ultraviolet photoelectron spectroscopy (UPS) and auger electron spectroscopy (AES). First the experimental setup is briefly described, followed by the support preparation and characterization as well procedures utilized in this work. These descriptions include a concise introduction to the underlying physical principles of the applied techniques (including experimental details). 

It should be pointed out that empirical potentials were not always used because ab initio results were not obtainable. An important use of classical trajectories is the inversion of experimental data to determine the potential. This was most productive in applications to crossed molecular beam reactive scattering data where trajectories were used to adjust PES features to reproduce the experimental results. This was one of the early rewarding efforts in the use of experiments to probe the explicit details of PESs. Currently, experiments are being done to probe directly the transition-state regions of PESs. Also, a lot of effort has been devoted to vibrational mode-selective behavior in chemistry, which could provide information about potentials at high energies. ...
