Electronic spectroscopy was used to obtain gas phase spectrum of the germanium carbide molecule in emission from a corona excited supersonic expansion source. The (2) 3Π – X 3Π electronic transition was observed around the 21250 cm-1 region. In this system, vibrational bands and the rotational lines of the Ω = 0, 1, and 2 components were obtained and analyzed. The equilibrium transition energy is found at 21120.3 cm-1 and the fundamental vibrational frequency for the lowest energy ground state Ω = 2 component is 795.3 cm -1. This is the first spectroscopic observation of germanium carbide.
An unsuccessful attempt to obtain the first electronic emission spectrum of aluminum boride is also described.
