Calculation of self-broadened widths of rotational Raman lines in H2 and N2

Abstract

Self-broadened widths of rotational Raman lines of S-branch in H2 and N2 are calculated in the impact and straight classical path approximation. A core potential of the form r−n is considered along with the quadrupole–quadrapole interaction. It is found that the results are sensitive to the core potential parameters. Comparison with experimental data yields values for these parameters.
