Summary:[Display omitted] ► First spectrum of germanium carbide. ► Many vibrational bands observed in the (2) 3Π–X 3Π system near 480 nm. ► Fundamental vibrational frequency is 795.3 cm −1. The gas phase spectrum of the germanium carbide radical has been observed at low temperature in emission from a corona excited supersonic expansion source. Many vibrational bands involving the Ω = 0, 1, and 2 components of the (2) 3Π–X 3Π system were recorded and analyzed. The equilibrium transition energy is found at 21120.3 cm −1, in good agreement with theoretical predictions. The fundamental vibrational frequency for the lowest energy ground state Ω = 2 component is 795.3 cm −1.
