Vacuum-ultraviolet photolysis of H_3CF in solid neon: Infrared spectra of HCF and CF~+

摘要

Irradiation of a sample containing fluoromethane dispersed in solid neon near 3.0 K with light from a synchrotron at wavelength 124 nm generated products that were detected with infrared absorption spectra. The identified products include CF, CF~+, CF_2, HCF, H_2CF, C _2F_2, C_2F_2H_2, CH _3, CH, C_2H_2 and HF. Isotopic labeling with ~(13)C and deuterium and quantum-chemical calculations confirmed the identification of these species; the vibrational spectra of CF~+ and HCF (CH stretching mode) are recorded for the first time in solid neon.
