Abstract
A strong absorption band of OH has been observed near 1221 Å. From the analysis of high resolution spectra, it has been determined that the upper state is a 2Σ− Rydberg state and the constants of the OH and the corresponding OD state have been obtained. It is shown that the new absorption band will give interstellar absorption lines of OH at 1221.166, 1222.071, and 1222.524 Å. New constants have also been determined for the A2Σ+ and X2Π states of OD.Keywords
