This paper presents a method for calculating the relative intensities and Raman shifts of the rotational structure in electronic Raman spectra of diatomic molecules. The method is exact in the sense that the wave functions used for the calculations may belong to any intermediate case of Hund's coupling schemes. Using this method, theoretical calculations of the pure rotational and electronic Raman spectrum of NO, and the pure rotational Raman spectrum of O2, are presented. Although a calculated stick spectrum for NO was previously shown by Fast et al., the details of this calculation are given here for the first time.

Explicit Expressions

Explicit expressions are obtained for the intensity distribution in the branches of 1Σ–3Δ, 3Σ–3Δ, and 1Π–3Δ bands. They are valid with satisfactory accuracy for any value of the coupling constant of the 3Δ state.

Transition Formula

The rotational Raman spectrum of gaseous NO was photographed with a spectral resolution of ~0.3 cm−1. In longer exposures the rotational structure of the electronic transition, [Formula: see text], was also observed. It consists of O, P, Q, R, and S branches and has an intensity distribution in accordance with theory.
