摘要：

New bound-free spectra of the K-2 3(3)Pi(g)(v, J) --> a(3)Sigma and 4(3)Sigma(u)(+)(v, N) --> a(3)Sigma(u)(+) transitions have been observed with the perturbation facilitated optical-optical double resonance experimental technique. Our analysis has led to a conclusion that the vibrational assignments of the 3(3)Pi(g) 9 and 4(3)Sigma(g)(+) ro-vibrational terms observed in Kim et a]. [J. Chem. Phys. 102 (1995) 6646] have to be corrected. New potential energy functions of the K-2 3(3)Pi(g) state, the 4(3)Sigma(g)(+) state, and of the a(3)Sigma(u)(+) state repulsive branch are proposed.
