Ultraviolet Absorption Spectrum

The (0–0) and (1–0) bands of the E–X transition have been observed in absorption at high resolution. The analysis of the (0–0) band identifies the E state as 1Π, thus confirming recent theoretical calculations. Λ-type doubling of the order of 0.2–0.3 cm−1 is observed at medium J values. The much weaker (0–0) band of 13C16O was also observed and analyzed. The pertinent spectroscopic constants for the E state of 12C16O are as follows: T00 = 92 930.04 cm−1, B0 = 1.9645 cm−1, and D0 = 6.50 × 10−6 cm−1. For the 13C16O molecule the corresponding constants are: T00 = 92 929.62 cm−1, B0 = 1.8773 cm−1, and D0 = 5.94 × 10−6 cm−1.

High resolution absorption spectra of N2 in the wavelength region 85.73–86.65 nm have been photographed at a reciprocal dispersion of 0.03 nm/mm in the second order of a 2400 line/mm grating by a 6.65 m vacuum spectrograph. The Rydberg transitions [Formula: see text] and [Formula: see text] are analyzed. Gross irregularities in line positions and intensities are interpreted in terms of homogeneous and heterogeneous perturbations among the vibronic levels c4(0), [Formula: see text], b′(18), b(22), b(23), and b(24). A multilevel deperturbation procedure is applied to these levels to produce deperturbed spectroscopic constants. The perturbation matrix elements with the largest values are those of the homogeneous interactions [Formula: see text] and c4(0) × b(23) = 7.3 cm−1, and that of the heterogeneous interaction [Formula: see text]. Term values established for the upper levels c4(0) and [Formula: see text] of the vacuum ultraviolet (VUV) bands are combined with the recent results of Suzuki and Kakimoto for the visible bands c4(0)–a″(0) and [Formula: see text] to obtain term values of the [Formula: see text] level.
