N2 - The IR absorption spectra of liquid OCS (T = 135(1) K) and of the following solutions-OCS + Ar (T = 90 K), OCS + N 2 (T = 90 K), OCS + Kr (T = 130 K), and OCS + Xe (T = 163 K)-are measured in the range 800-7000 cm -1 . From 16 to 40 bands corresponding to transitions to vibrational states up to the third order inclusive are interpreted for basic isotope modification and for the isotopically substituted molecules 18 O 12 C 32 S, 16 O 13 C 32 S, and 16 O 12 C 34 S. In the spectra of the liquids, the spectral moments M(1) and M(2) of all the observed bands are determined. The harmonic frequencies ω i and the anharmonicity constants x ik are calculated for all the systems, including the liquid. The anharmonicity is found to be constant within the experimental error. A large shift Δω 3 is primarily determined by the dipole-induced dipole interaction.
