Electron transport coefficients in carbon monoxide and deuterium

The drift velocity and the ratio of transverse diffusion coefficient to mobility have been measured for electrons in gaseous carbon monoxide and deuterium at 293 K. The measurements were made under conditions where vibrational excitation is the major energy loss in order to resolve some discrepancies that exist between published vibrational excitation cross sections for these gases. The results are in good agreement with the majority of the existing data where available, but the error bounds are reduced significantly in some cases.
