Concave grating spectrograph; vibrational constants; rotational constants; spin splitting; microwave optical double resonance (MODR); laser fluorescence; head-head separation

The spectrum of the C²II-X²Σ system of SrF molecule has been investigated under high resolution. The rotational structure in the (0, 0) band has been analysed and the rotational constants for the C²II state have been obtained. The vibrational analysis of this system has been carried out using the band heads from the high resolution spectrogram and also the band origins and the precise vibrational constants have been reported for both the participating states.
