Liquid‐Gas Infrared Intensities, Pressure‐Induced Absorption, and the Temperature Dependence of Infrared Intensities in Liquids

Abstract: The recent paper by Polo and Wilson eliminates the apparent discrepancy between the equations given for the relationship between intensities of a compound in the gas phase and the intensities in the liquid phase. However, the experimental tests of this equation have not been conclusive. This paper applies their equation to the pressure‐induced absorption of methane, and to the temperature dependence of the integrated intensities of liquid cyclohexanone and liquid benzene. The treatment of Polo and Wilson is extended to give an equation which is valid for solutions. In all cases, qualitative agreement is obtained between experiment and calculation and it would seem that the effect of index of refraction on the intensity accounts for a significant part of the changes observed. The agreement for benzene and for the pressure‐induced absorption of methane is excellent.

Vibrational Intensities. IX. C2F6: Extension and Revision

Abstract: The intensity of the low fundamental of C2F6 at 219 cm—1 was measured using a CsI prism. This completed earlier studies on the other fundamentals, and permits extension and revision of the interpretation. Effective bond moments are compared with those of other fluorocarbons.
