“…In 1927, Mulliken published a detailed theoretical interpretation of the spectra of a number of diatomic molecules, including OH . The experimental work was later extended by Johnston and co-workers − using improved experimental apparatus and longer photographic exposure times. Since then, there has been a large number of investigations of gas-phase OH and (to a lesser extent) OD …”

Magnetic circular dichroism (MCD) and absorption spectra are reported over the temperature range 1.7−7 K and the magnetic field range 0−4 T for the hydroxyl free radical isolated in an Ar matrix (OH/Ar). The data indicate a reduction of the orbital angular momentum of the lowest electronic level of the guest. This is interpreted within the framework of a crystal field model involving the Ar atoms of the host lattice. The conclusions are that the OH guest radicals are randomly oriented, occupy at least five distinct sites, and have orbital reduction factors in the range κ = 1.00 to 0.54.

The investigations begun in the neighborhood of the (0',1") band at X3428 (cf. reference 4) have been extended to include the bands of the (0,0) and (l',0") sequences. Approximately 400 lines were observed in this region of the spectrum, of which 120 are reported for the first time. All but 18 of these have been successfully assigned. The assignments include the identification of a new (2,2) band with its principal head at A3185; the identification of RR R2i and of pp Pi2 satellite r branches of the (1,1) band; complete assignments of the regular i?-branches of the (1,1) and(2',1") bands; and extensions of nearly all the remaining branches of the bands which appear in this region. The new data are also utilized to obtain A-doublets and spin doublets to K = 35 for the 0" level and to somewhat smaller values of K for the 1" and 2" levels. The experimental results are compared with equations in the literature. Molecular constants derived from the new (2,2) band are in good agreement with those derived from the {V,2") band.
