Raman intensities of overtones and combination bands of C2H2, C2HD, and C2D2thinsp;@fa@f)

摘要

Measurements of absolute gas phase vibrational Raman scattering cross sections of binary overtone and combination bands of C2H2,C2HD, and C2D2are reported. Calculated values for these cross sections, which take into account the contribution of the anharmonic force field and the electrohyphen;optical anharmonicity, are also presented. Within limitations due to approximations in the theory and uncertainties in the parameters, the comparison between the experimental cross sections and the calculated ones is quite encouraging.
