Abstract:
The differential cross section for the excitation of infra-red inactive and — in dipole approximation — infra-red active fundamental vibrations by fast electrons is calculated. The energy loss spectra of CO2, N2O, C2H4 are measured with 33 keV electrons in the small energy loss range up to 0.5 eV. The experimentally determined “particular” cross sections
