Abstract

Methyl and methylene fragments are achieved using a complete set of quantum yields for different photodissociation channels. The results depicted that the hydrogen (H) atoms are more abundant in photofragments than deuterium (D) atoms. The ultraviolet absorption spectrum of methane is identical at different temperatures. The quantum yields of H atoms are determined by the measurement of the ratio of areas under the laser-induced fluorescence excitation curves.
