Measurements of the optical absorption spectra of the sublimed films of adenine, guanine, cytosine, thymine, and uracil were extended down to 120 mp at room temperature. Several remarkable absorption peaks were found to exist below 190 mp in addition to the already known ones near 260 mp and 200 mp.
The vacuum-ultraviolet spectra from 200 to 120 nm of BFJ, BC13 and BDrs are reported. Tentative assignments are made. The lowest frcqucncy band of DC13 and BBr3 can be assigned to a valence-shell transition of the ?I\* + n type. The second band can be described equnll?r well 3s a Rydberg tr~lsition
