Abstract

The 0(0)(0) bands of the (A) over tilde(2)B(2)-(X) over tilde(2)A(1) and (B) over tilde(2)B(1)-(X) over tilde(2)A(1) systems of SrNH2 were observed at Doppler-limited resolution using a Broida oven source and laser-induced fluorescence detection. A full rotational analysis of both transitions was performed including K-a, levels up to 5 and J levels up to 55. The (B) over tilde(2)B(1), state was found to be extensively perturbed and only some of the subbands could be analyzed. The (A) over tilde(2)B(2), and (B) over tilde(2)B(1), states undergo a strong Coriolis-type interaction which results in extremely large spin-rotation splittings in both states, effectively splitting all levels with K-a' not equal 0 into two well-separated spin components.
