Vibrational Intensities. XI. CO2 and the Wilson-Wells Method

Abstract

The Wilson‐Wells‐Penner‐Weber method of determining absorption‐band intensities in the infrared has been critically reviewed. This technique has been used to redetermine the intensity of the 670 cm^—1 band system of carbon dioxide. The present result, A=241 cm^—1/cm atmos at STP agrees well with the curve‐of‐growth value, A=240 cm^—1/cm atmos at STP and demonstrates that, with proper precautions, both methods are capable of producing reliable intensity data.
