The static polarizability and the cross sections for Rayleigh and rotational Raman scattering in molecular nitrogen are calculated by a direct perturbation technique. This approach is based on an effective intermediate state energy approximated closely through knowledge of potential energy curves for the nitrogen electron states. Results obtained for the static polarizability agree with experimental values within about 20 per cent and represent considerable improvement over earlier calculations. The cross section for Rayleigh scattering is given for various polarizations and scattering angles, and is found to agree with experiment within about 30 per cent. The rotational Raman forward scattering cross section is obtained as a function of rotational level, and Stokes scattering cross section is obtained as a function of rotational level, and Stokes scattering from the J = 6 level is shown to be most easily stimulated in Raman lasers at room temperature, for illumination by ruby laser light.
