Quantum calculations for resonant vibrational excitations of cyclopropane by electron impact

摘要: We present calculations of the vibrational excitations three normal modes cyclopropane molecule in gas phase: ν1 C-H stretching mode, ν2 H-C-H scissoring mode and ν3 C-C mode. The excitation processes occur by electron-impact inelastic scattering within energy range where resonant occurs, according to existing experiments. quantum employ single-centre-expansion-close-coupling method treat process contributions are obtained adiabatic nuclear vibration approximation scheme. results shown be rather good accord with experiments most likely microscopic mechanisms which preside over these electron impact at resonances discussed some detail.
