MoN and MoO molecules produced in a hollow cathode discharge have been trapped in Ne, Ar, and Kr matrices at 4.2 and 13 K and investigated by optical spectroscopy. Bands attributed to MoN were identified in the red and blue spectral regions and assigned by comparison with gas phase results to the A/sup 4/..pi.. ..-->.. X/sup 4/..sigma../sup -/ (a) and B/sup 4/..sigma.. ..-->.. X/sup 4/..sigma../sup -/ (a) transitions, respectively. The ground state of Mo/sup 14/N has been identified as /sup 4/..sigma../sup -/ with ..omega../sub e/ = 1040 cm/sup -1/ in an Ar matrix. Absorptions assigned to MoO in the red spectral region form the (0-0) and (1-0) bands of at least one electronic transition, but could not definitely be correlated with the gas phase results. The ground state vibrational frequency for Mo/sup 16/O in an Ar matrix is 893.5 cm/sup -1/. Additionally, Mo/sub 2/ absorptions centered at 19 305 cm/sup -1/ were shown to be part of a vibrational progression with an average spacing of 181 cm/sup -1/.
