DEPERTURBATION OF THE NA-2 4(3)SIGMA(+)(G) UPSILON=4 SIMILAR-TO 3(3)PI(G) UPSILON=6 AND 4(3)SIGMA(+)(G) UPSILON=14-SIMILAR-TO-2(3)PI(G) UPSILON=68 INTERACTIONS

The 4(3) Sigma(g)(+) upsilon = 4 similar to 3(3) Pi(g) upsilon = 6 and 4(3) Sigma(g)(+) upsilon = 14 similar to 2(3) Pi(lg) upsilon = 68 perturbations of Na-2 have been observed by perturbation facilitated optical-optical double resonance spectroscopy via b(3) Pi(u) upsilon' = 14 intermediate levels. Deperturbation of the 4(3) Sigma(g)(+) upsilon = 4 similar to 3(3) Pi(g) upsilon = 6 interaction has been performed and deperturbed values of T-upsilon, B-upsilon, and the rotation-electronic perturbation parameter have been obtained. The 4(3) Sigma(g)(+) upsilon = 14 similar to 2(3) Pi(g) upsilon = 68 perturbation belongs to a local 2 X 2 perturbation and the perturbation matrix element has been derived. Quantum interference has been observed in both the excitation and resolved fluorescence spectra into the b(3) Pi(u) state. (C) 1995 Academic Press, Inc.
