ABSTRACT

Green 1977

Green, S., 1977: Rotational excitation in collisions between two rigid rotors: Alternate angular momentum coupling and pressure broadening of HCl by H2. Chem. Phys. Lett., 47, 119-122, doi:10.1016/0009-2614(77)85320-7.

In order to compute relaxation "cross sections" for molecule-molecule collisions it is convenient to employ a coupled angular momentum representation which differs from that generally used. An explicit expresion for collision-induced spectral pressure broadening in this representation is given, and this is used to examine the difference between para- and ortho-H2 for broadening of HCl.
