摘要：

Recent measurements of electron drift velocities in carbon dioxide at 573K have been found to be incompatible with momentum-transfer cross sections derived by analysis of electron transport coefficient data for room and lower temperatures. An explanation is proposed in terms of electron scattering from carbon dioxide molecules in the first vibrationally excited state. The conventional two term assumption in the solution of theBoltzmann equation has been investigated for the case of CO2 and found to be inadequate. The implications of this finding for the derivation of vibrational excitation cross sections for CO2 are discussed.
