The spectroscopy and photoabsorption cross sections of nitrosyl fluoride are investigated in the spectral region 350-180 nm. Results for 350-250 nm are in good agreement with the initial measurements of Johnston and Bertin and later measurements from Solgadi and Flament and Huber et al. The spectrum is assigned to a series of vibrational progressions which arise from (0, 0, 0)[double prime] and involve excitation of the [nu][sub 1][prime] mode. Excitations to (n, 0, 0)[prime] and (n, 0, 1)[prime] make up the bulk of the spectrum, with promotions to (n, 1, 0)[prime], (n, 0, 2)[prime], and (n, 1, 2)[prime] becoming dominant at higher energies. Analysis of the spectrum results in values of [nu][sub 1][prime] = 1,096 cm[sup [minus]1], [nu][sub 2][prime] = 480 cm[sup [minus]1] and [nu][sub 3][prime] and [nu][sub 3][prime] is distinctly stronger than that for [nu][sub 2][prime]. Below 250 nm, a broad, featureless continuum absorption is observed, which rises in intensity from [sigma] = 1.77 [times] 10[sup [minus]20] cm[sub 2] at 245 nm to 5.24 [times] 10[sup [minus]19] cm[sub 2] at 180 nm.
