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 H2 was used as the sputter gas in the dc plasma discharge. The bandheads were observed at 16,560 cm-1, 16,485 cm-1, 16,027 cm-1, and 15,960 cm-1. Four rotational branches have been identified in each transition, and the transitions have been fit to two 2Σ - 2Π transitions using PGOPHER, with spin-orbit splittings in the Hund’s case (a) Π-states of 75 cm-1 and 67 cm-1. There are no common states between the two transitions. The transitions have tentatively been assigned to the linear molecule HCuN. Results of this analysis will be presented
