Abstract
Extensive measurements of magnetic dipole transitions in the gas phase E.P.R. spectrum of NO2 in its [Xtilde] 2 A 1 state are reported. This type of transition was first identified by Burch, Tanttila and Mizushima. The data have been fitted simultaneously with measurements from the far infra-red laser magnetic resonance spectrum of NO2 to determine the principal components of the electron spin g-tensor. The results are consistent with Curl's relationship between the components of the electron spin and spin-rotation tensors. It is necessary to include the effects of centrifugal distortion of the spin-rotation interaction and two parameters describing this interaction are determined in the course of the analysis. Some discussion of the origins of these parameters is included.Keywords
