Abstract

Self-broadening of the rotational Raman lines of O2, N2, CO2, and CO, and foreign-gas broadening of O2 and N2 by He and Ar were measured in the pressure range from 7 to 43 atm at room temperature. Spectrograms were obtained with Hg 2 537 Å as exciting line and a reciprocal linear dispersion of 11.2 cm−1 per mm. In each case the broadening was found to be proportional to the pressure so that a broadening coefficient [Formula: see text] could be defined. The broadening coefficient shows a monotonie decrease with increasing rotational quantum number J. The values of [Formula: see text] for N2 and their variation with J are in good agreement with the values calculated theoretically by Van Kranendonk on the basis of quadrupolar interaction in the impact approximation.
