F. Barocchi et al., DENSITY EVOLUTION OF THE DOUBLE ROTATIONAL TRANSITION IN CONDENSED PARAHYDROGEN, Physical review. B, Condensed matter, 55(18), 1997, pp. 12223-12234
The Raman intensity of the forbidden S-0(0)+S-0(0) transition has been
measured both in the liquid acid in the solid phase. The detailed the
ory of the integrated intensity of such forbidden spectra is presented
which involves the pair correlation function of the system together w
ith the anisotropic components of the intermolecular potential and cer
tain components of the collision induced polarizability. The experimen
tal results are compared with the numerical evaluations obtained with
models for the intermolecular potential and collision induced polariza
bility that are taken from literature.
