Abstract
The emission spectrum of a plasma of silane and nitrogen, excited by a radio frequency discharge, has been recorded with a high resolution Fourier transform spectrometer. We report here the first observation by IR spectroscopy of the X $^2 \Sigma^+ (v=1, 2)$ and A $^2 \Pi_{\rm i} (v=2, 3, 4)$ vibrational levels of 28Si 14N, through the observation of 724 unperturbed transitions of the (1-0), (2-0), (2-1), (3-1), and (4-2) vibronic bands of the A $^2 \Pi_{\rm i}$ - X $^2 \Sigma^+$ system of this radical. The data were analyzed in a least squares fit procedure, with a standard deviation equal to $6\times10^{-4}$ cm -1.
