Absolute Infrared Intensities of Some Linear Triatomic Molecules in the Gas Phase

Infrared intensities for the low-frequency bending vibrations ν3 have been measured by the curve-of-growth method for N2O, COS, and CS2 in the gas phase. The intensity of ν3 for gaseous COS has been measured by the same method. These results help to determine which of the values reported previously are to be preferred. These preferred values are listed for the intensities of all the fundamental vibrations.
