A 2 Π 1 2 (v′= 0)-X 2 Σ (v ″= 0) subband system of SrH have been recorded at sub-
Doppler resolution using the technique of intermodulated fluorescence. The recorded
spectra exhibit a small splitting associated with magnetic hyperfine interactions in both the
ground and the excited electronic states. An analysis of the excited state contributions was
performed and the results were interpreted in terms of the possible nature of the electronic …
