Fluorescence spectra of the Cd2 dimer: transitions involving 0u+ and 1u Rydberg states and the lowest excited gerade states

Absorption and emission studies of the (51S0)–1u(63S1) transition in the Cd dimer

“…It was also shown in [1] that the dissociation limits for the upper states were situated above the respective atomic asymptotes. This was particularly evident for the 1 u (6 3 S 1 ) state, indicating the presence of a barrier in the potential energy curve of this state.…”

“…In our recent paper [1] two Cd 2 Rydberg states, 0 þ u and 1 u , correlated with the 6 1 S 0 + 5 1 S 0 and 6 3 S 1 + 5 1 S 0 asymptotes, respectively, have been identified spectroscopically and the shapes of both potential energy curves were discussed. Following those studies, further experiments have been performed in the present work, yielding additional data concerning these states.…”

“…The first quantitative results regarding the 0 þ u (6 1 S 0 ) and 1 u (6 3 S 1 ) excited states were obtained in [1] from observation and analysis of several v 0 progressions terminating in the lowest excited gerade states of the 5 3 P 0,1,2 + 5 1 S 0 asymptotes predicted by theoretical studies [6,7]. In each case studied, the v 0 fi v 00 = 0 progressions were observed almost up to their dissociation limits.…”

“…This was particularly evident for the 1 u (6 3 S 1 ) state, indicating the presence of a barrier in the potential energy curve of this state. Its height was determined in [1]. Based on data available for the ground state potential of Cd 2 [8] and on the aforementioned information, we can put forward two hypotheses:…”

Experimental studies of the 200 nm diffuse band in zinc vapour and its interpretation

“…Moreover, basing on the combining results of that paper with findings derived from the extensive studies of fluorescence spectra of the Cd vapour following strong laser excitation [6,34], in [7] we have argued that the 1 u ( …”
