Abstract

Four new electronic transitions with blue-degraded bandheads were observed in the orange-red region of the visible spectrum. The transitions were observed in the plasma discharge of a hollow copper cathode placed within the cavity of a tunable dye laser system, allowing molecular absorbance to be enhanced upon laser amplification. To produce the molecules, the surface of the copper cathode was soaked in a dilute ammonia solution prior to installation, and 1 torr of chem{H_2} was used as the sputter gas in the dc plasma discharge. The bandheads were observed at 16,560 wn, 16,485 wn, 16,027 wn, and 15,960 wn. Using 1.5 torr of chem{D_2} as the sputter gas resulted in a -3 wn shift in origin for the bands in the ~16,000 wn region. Four rotational branches have been identified in each transition, and the transitions have been fit to independent $^{2}Sigma$ - $^{2}Pi$ transitions using PGOPHER, with spin-orbit splittings in the Hund’s case (a) $Pi$-states of -71.2 wn and -65.4 wn. The transitions have tentatively been assigned to HCuN. Results of this analysis will be presented.
