Infrared Spectrum of S16O18O and the Potential Constants of SO2

摘要

An investigation of the infrared spectrum of S16O18O results in the following frequency assignment:ngr;1equals;1122plusmn;1thinsp;cmminus;1,thinsp;thinsp;ngr;2equals;506.8plusmn;0.5thinsp;cmminus;1,thinsp;thinsp;ngr;3equals;1341plusmn;0.5thinsp;cmminus;1.These data combined with the fundamental frequencies of S16O2have been used to calculate the potential constants for sulfur dioxide. These arefdequals;10.02,thinsp;thinsp;fddequals;0.03,thinsp;thinsp;1dfdagr;equals;0.20,thinsp;thinsp;1d2fagr;equals;0.793.
