High-Resolution Laser Spectroscopy of the Ã(2)B(2)-&Xtilde;(2)A(1) and &Btilde;(2)B(1)-&Xtilde;(2)A(1) Systems of SrNH(2).
The 0(0)(0) bands of the Ã(2)B(2)-&Xtilde;(2)A(1) and &Btilde;(2)B(1)-&Xtilde;(2)A(1) systems of SrNH(2) 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 &Btilde;(2)B(1) state was found to be extensively perturbed and only some of the subbands could be analyzed. The Ã(2)B(2) and &Btilde;(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.
