英文摘要	the na2 b 3pi(u) state has been studied by the continuous wave (cw) all-optical triple resonance (aotr) technique. the aotr technique used here corresponds to a perturbation-facilitated optical-optical double resonance (pfoodr) excitation through a 1sigma(u)+ approximately b 3pi(u) mixed intermediate levels from the ground state to the 2 3pi(g) state and stimulated emission pumping (sep) of the 2 3pi(g) --> 3pi(u) transition. this sub-doppler high-resolution pfoodr-sep technique has allowed us to reach many b 3pi(u) levels (omega=0, 1, 2, perturbed and unperturbed, including low v below the a1 sigma(u)+ potential minimum and higher vibrational levels up to v = 57). based on these new high resolution data and previous results from high resolution spectroscopy, we have determined a new set of deperturbed molecular constants from the b 3pi(u) state up to nu=57, the corresponding rkr potential energy curve and the a 1sigma(u)+ approximately 3pi(u) spin-orbit interaction constants. this represents an example of a powerful and general technique for observing a "dark" (e.g., triplet) perturbing state when only the "bright" (e.g., singlet) perturbed state is well known from single photon spectroscopy.
