Integral cross sections (ICS) for electron impact vibrational excitation of CO_2 molecule have been used to calculate electron energy transfer rate coefficients for the equilibrium electron energy distribution conditions. Symmetric stretch vibrational excitation cross sections are measured by using our high resolution trochoidal electron spectrometer. ICS for bending and asymmetric vibration of CO_2 have been adopted from previous results. Total and partial electron energy transfer rate coefficients for vibrational excitations are calculated by use of the Maxwellian electron energy distribution function (EEDF) and by direct numerical integration of experimental cross sections. These preliminary calculations have been compared with the previous results.
