Abstract
The ultraviolet emission spectrum of GeH has been examined following the two photon-initiated dissociation of germane (GeH4) at 248 nm. The most prominent peaks lying between ∼250 and 340 nm are tentatively assigned to B 2Σ (v′ = 0)→X 2Π 1/2,3/2 (v″) transitions. From this premise, the vibrational constants for the X 2Π states have been estimated to be ωe = (1949 ± 5) cm-1, ω exe = 16.5 ± 2.0 cm-1, and ωeye = (0.7 ± 0.3) cm-1. Also, the radiative lifetime of the lowest vibrational levels of the GeH A 2Δ state in transitions to ground has been measured to be 12 ± 2 ns.
