| Abstract: | The gold vapor laser has been used to irradiate the alkali dimers Li2, Na2, K2, and Rb2. Significant fluorescence was found only from Na2 and K2. Six fluorescent series in the A1Σu+-X1Σg+ system of Na2 and three in the B1Πu-X1Σg+ system of K2 were assigned, respectively. New spectroscopic constants for the X1Σg+ state of 39K2 are derived, and new RKR potential energy curves for the X1Σg+ and B1Πu states of 39K2 are given. |
