| Abstract: | Electron energy peak shifts and peak shapes were determined in the ionization of H2O, D2O, H2S and SO2 by Ne(3P2) and He(21S, 23S) metastable atoms. The shifts are large, especially in ionization of H2O and D2O into the ionic ground state and are probably mostly due to chemical interaction during the collision.In a previous paper the electron energy distribution curves for ionization of CO, HCl, HBr, N2O, NO2, CO2, COS and CS2 by helium, neon and argon metastables and the characteristics of this ionization were described1. In this paper the series of triatomic molecules was extended to the molecules H2O, D2O, H2S and SO2. Because all these molecules have considerable dipole moments it could be expected that the peak shifts might be enhanced as compared with other triatomic molecules. |
