Ml. Dubernet et al., Investigations of pure rotational transitions of H-2 perturbed by He. II. High-temperature calculations and extrapolations, J CHEM PHYS, 114(3), 2001, pp. 1286-1294
Close-coupling calculations of broadening and shifting coefficients of Rama
n S-0(j) lines of H-2 perturbed by He are performed up to 3000 K. They are
used to test two approximate methods, the quantum coupled states theory and
the RB semiclassical model. They are further applied to study the use of s
imple functional forms for fitting and extrapolating experimental data, and
some new fits of experimental broadening coefficients are given. (C) 2001
