Multiphoton fragmentation and ionization of CF{sub 2}HCl molecules and clusters by UV radiation
The results of experimental studies of multiphoton ionization of CF{sub 2}HCl molecules and clusters by UV laser radiation in the wavelength range 217-236 nm are reported. In the case of molecules, the main reaction products are CF{sub 2}H{sup +} and CF{sup +} ions as well as atomic chlorine. It is found that the spectra of the products of ionization of free molecules and molecules condensed into clusters differ qualitatively: multiphoton ionization of clusters does not yield CF{sub 2}H{sup +} ions. The dependences of the ion yield on the intensity of laser radiation and its wavelength are measured. The effect of a constant electric field and the radiation spectral width on the multiphoton ionization process is demonstrated. The shape of the velocity distributions is determined for a number of products. A strong anisotropy is detected in the reaction of formation of CF{sub 2}H{sup +} ions. Possible mechanisms for these processes are discussed.
