The pure rotation spectrum of OH and the solar oxygen abundance
Abstract
High-resolution low-noise spectroscopic observations of the sun obtained in the 10.6-13-micron range using the Fourier-transform spectrometer at Kitt Peak National Observatory are reported. About 100 pure rotation lines of the X 2Pi electronic state of OH with v = 0, 1, 2, and 3 are identified and characterized. The data are presented in tables and graphs and used to calculate the solar O abundance as 8.91 + or - 0.01 (in agreement with Lambert, 1978). Agreement is also found with the electric-dipole-moment function of Werner et al. (1983) and the photospheric model of Holweger and Mueller (1974).
