摘要：

The K-39(2) 2 (3)Pi(g) state has been observed by perturbation facilitated infrared-infrared double resonance and two-photon excitations. The vibrational numbering of the 2 (3)Pi(g) levels was determined by resolved fluorescence into the bound levels as well as to the continuum of the a (3)Sigma(u)(+) state. The rotational assignment of the 2 (3)Pi(g) levels excited by two-photon transitions was determined from excitation frequencies and resolved fluorescence into the bound levels of the a (3)Sigma(u)(+) and b (3)Pi(u) states. Molecular constants obtained from these observed levels agree with theoretical constants. (C) 2005 American Institute of Physics.
