Abstract:

Developed is a new technique and apparatus for studying photodestruction processes in molecules. Proof of method experiments have been carried out using H2 as the prototypical molecule. A paper describing this work has been submitted to the Review of Scientific Instruments. Application of the method to polyatomics and more than two fragments per dissociation event has been investigated. Beams of the ions of nitromethane and its fragments have been produced in sufficient quantities fo experimentation using our technique. The absorption spectrum of nitromethane has been measured in the range 190-300 nm with 0.001 nm resolution. A feasibility study of induced fluorescence experiments to determine the spectra of polyatomic free radicals has been carried out. Experiments on the photodissociation of CH and OH and CH have been initiated. Keywords Photodissociation Molecular beams Hydrogen molecular ion.
