Fourier Transform Spectra of the A2Σ+ (v=0) -X2∏ (v=o) Band of OH

Abstract

The hydroxyl radical plays an important role in a variety of atmospheric, astrophysical, and chemical processes. Both absorption in, and fluorescence from, the strong (0-0) band of the A2Σ+ - X2∏ system are widely used in concentration measurements of OH (e.g., Stimpfle et al. 1990; Desgroux and Cottereau 1991).
