FERMI DIAD 10°0 AND 02°0 OF NITROUS OXIDE

Abstract

Measurement of the fine structure of the bands ν 1 and 2ν 2 0 of nitrous oxide has led to an evaluation of the centrifugal stretching constants of the Fermi diad 10°0 and 02°0. It was found that as compared to the value in the ground state, the change in the centrifugal stretching constant of the 02°0 level is much more than in the 10°0 level. This result has been discussed in relation to the theory of Nielsen, Amat, and Goldsmith (1956). The following revised values have been obtained for some of the molecular constants of N 2 14 O 16 :[Formula: see text]
