Absorption and Photoionization Cross Sections of H2O and H2S

Absorption and photoionization cross sections of H2O in the region 850–1110 A and H2S in the region 1060–2100 A were measured by photoelectric methods. The absorption curves support the photographic study of H2O and H2S by Price. The photoionization curves yielded the following ionization potentials: 12.62 eV for H2O and 10.46 eV for H2S.
