Characterization of bound parts of the b(3)0(u)+(5(3)P(1)), c(3)1(u)(5(3)P(1)) and X(1)0(g)(+) states of Cd-2 revisited: Bound-bound excitation and dispersed emission spectra
Laser-induced fluorescence excitation and dispersed emission spectra of Cd-2 recorded using the c(3)1u(5(3)P(2))<- X(1)0(g)(+) and b(3)0(u)(+)(5(3)P(1))-> X(1)0(g) transitions, respectively are reported. In the excitation to the c(3)1(u) state, red-shaded vibrational components of several nu'<- nu" = 0, 1, 2, 3 progressions and Delta nu = 0,1 sequences were identified. In the emission from the b(3)0(u)(+) state, well resolved nu' = 0,1,2,3,4 ->nu" transitions were recorded using a spectrograph with CCD camera. Analyses of the spectra provided an improved characterization of the b(3)0(u)(+), c(3)1(u) and X(1)0g(+) states involved in the transitions. The results were compared with our ab initio calculations and those obtained experimentally in earlier studies. (C) 2010 Elsevier B. V. All rights reserved.
