Abstract : The low energy electron collisions with H20 and H2S have been studied for elastic and rotational excitation channels. A parameter-free ab initio approach is employed in which electron exchange interaction is treated exactly and the polarization effects via perturbation theory. The integro-differential coupled equations are solved iteratively to yield scattering parameters. Detailed results are obtained for differential, integral, and momentum transfer cross sections. The agreement with experimental data for all the parameters is very good. The intermediate and high energy electron scattering with a large number of diatomic and polyatomic molecules is studied between 20-5000 eV and results for total (elastic plus inelastic) cross sections are reported.
