Abstract
The 0–0 band of the b1Σ+ – X3Σ− system of the NF molecule has been measured in emission using a Fourier-transform spectrometer. The line assignments of Douglas and Jones are confirmed, but their statement regarding the relative size of the parallel and perpendicular transition moments is incorrect. From a least squares fit of the line intensities, we determine the value μ1/μ0 = 0.261 for the ratio of the perpendicular (μ1) and parallel (μ0) transition moments. This value lies between two recent ab initio estimates, 0.96 and 0.049.Keywords
