Description

With the aid of nanosecond laser flash photolysis OH is chemically produced and observed 'collision free'. The rotational states show inverted population in the Λ doublets J'' = 3/2, 5/2, 7/2, and 9/2 of 2PIsub(3/2) and anti-inversion in the higher rotational states. The intensities of the main and satellite absorption lines further indicate an inversion in special hyperfine states. Application to interstellar OH maser emission is considered. (orig.)
