Paper Abstract

As part of a global analyis of the infrared spectrum of chloromethane, the region of the fifth polyad involving the upper states of seven interacting bands 2υ6, υ23, υ35, 3υ3, υ26, υ56, 2υ36, from 1900 to 2600 cm-1 has been re-investigated. More than 20 000 transitions for each isotopomer 12CH335Cl and 12CH337Cl have been assigned and fitted with a standard deviation better than 4 10-4 cm-1 close to the experimental precision. The present paper is focussed on the determination of the ground state constants of 12CH337Cl by exploiting in a global theoretical model perturbation-allowed transitions already observed for 12CH335Cl by Di Lauro and Alamichel (J. Mol. Spectrosc. 81, 390-412 (1980)).
