• Experimental processes recently developed to determine differential and partial photoionization cross sections of molecules are described in detail, based on photoelectron intensity measurements using a gaseous binary mixture of a sample with a standard gas. The quantities obtained here in these processes are 1) relative photoelectron peak heights, 2) normalized photoelectron spectra, 3) relative photoelectron band areas, and 4) differential and partial photoionization cross sections. Corrections are made for electron collecting efficiency. In connection with the photoelectron intensity determination, we propose here a method of obtaining the mole ratio of the components of a binary mixture entered into the ionization chamber of a photoelectron spectrometer. Satisfactory results on partial photoionization cross sections have been obtained for several testing samples.
