Abstract
The global analysis of the infrared spectrum of chloromethane involving the ground state and the 13 vibrational states lying up to 2600Â cmâ1 is reported. This work incorporates and extends to the fifth polyad, the preliminary study of the lower four polyads published by [J. Mol. Spectrosc. 221 (2003) 199]. More than 20Â 000 transitions (including numerous hot bands) for each isotopomer 12CH335Cl and 12CH337Cl have been assigned and fitted with a standard deviation of about 3Â ÃÂ 10â4Â cmâ1 close to the experimental precision. A common set of 288 (resp. 303) effective parameters was determined for each isotopomer. Our global model allowed us to reproduce simultaneously and accurately the resonances already encountered in Polyad 3 and the new ones involved in Polyad 5.
