摘要：

We present new c (3)Sigma(+)--> a (3)Sigma(+) laser induced fluorescence spectra of the NaK molecule, which clearly indicate that v(0) = 20 is the first vibrational level of the c (3)Sigma(+) state lying above v = 0 of B (1)Pi state. These spectra are used in a multistep deperturbation (B (1)Pi similar to c (3)Sigma(+) similar to b (3)Pi) procedure to obtain improved a (3)Sigma(+), b (3)Pi and c (3)Sigma(+) potential energy curves. The deperturbation analysis is confirmed by the calculated electronic B (1)Pi similar to c (3)Sigma(+) and c (3)Sigma(+) similar to b (3)Pi spin-orbit matrix elements obtained from many-body multipartitioning perturbation theory employing the relativistic effective potential method.
