title: Measurement of CO(2) line broadening in the 10.4-microm laser transition at low temperatures.
abstract: The broadening of CO(2) rotation-vibration lines has been investigated in the 200-300 K temperature range. From an analysis of four lines (|m| = 8, 15, 20, 30), it is found that the temperature exponent is nearly independent of the rotational quantum number within the limits of experimental error, for both self- and oxygen broadening. Average values n(1) = 0.86 for CO(2)-CO(2) and n(2) = 0.94 for C0(2)-0(2) have been obtained. Comparison is made with the results of the theoretical calculation based on the Robert-Bonamy model.
