Abstract

The absolute intensity of the infrared stretching vibrations of the molecules CS2 and OCS have been measured. For CS2, the intensity of ν3 was found to be 7560×1010 cycles sec−1 (cm of vapor at NTP)−1. For OCS, the results were 110 and 7900×1010 for ν1 and ν3. A normal coordinate analysis of the stretching vibrations of OCS was carried out to obtain ∂μ/∂r for the bonds and to compare them with those for CS2 and the previously obtained results for CO2. The results for a reasonable value of the interaction constant were 6.7 and 4.3×10−10 esu for the CO and CS bonds, while in CO2 and CS2 they were 6.0 and 5.6×10−10 esu. The bearing of these results on the amount of resonance in OCS is discussed. Arguments are presented which suggest that, in spite of the electronegativity difference between oxygen and sulfur, resonance in OCS is not markedly different from that in CO2 and CS2.
