Experimental and theoretical studies of the fundamental bands of sulfur dioxide

摘要

The infraredhyphen;active vibrationhyphen;rotation fundamentals of32S16O2have been measured with moderately high spectral resolution. Quantum number assignments have been made for spectral lines by comparison with theoretically computed line positions and intensities, which include the effects of centrifugal distortion. The following values for the band centers have been determined:ngr;1deg; equals; 1151.65 plusmn; 0.10thinsp;cmminus;1, ngr;2deg;equals;517.75plusmn; 0.10thinsp;cmminus;1, andngr;3deg;equals;1362.00plusmn; 0.10thinsp;cmminus;1.
