Abstract:

The absolute photoionization yields of carbon disulfide, carbonyl sulfide, methyl chloride, methyl bromide, methyl iodide, ethyl chloride, ethyl bromide, ethyl iodide, methyl formate, ethyl formate, benzene, benzenethiol, and mesitylene were determined for a number of wavelengths in the region 1070 A to the ionization cutoff of the molecule. Carbon disulfide and methyl iodide exhibited yields of about 90 percent between the region 1120-1200 A and 1080-1220 A, respectively. The yields for methyl chloride, ethyl chloride, methyl formate, and ethyl formate were much lower and decreased more rapidly towards longer wavelengths than that of the other molecules. With the exception of methyl chloride and carbonyl sulfide, the ionization potentials obtained were in agreement with the spectroscopic and photoionization values. Ionization potentials of the doublet state of carbon disulfide, carbonyl sulfide, and the alkyl halides were obtained. The second ionization potential was obtained for benzenthiol. Author
