| Abstract: | Synchrotron radiation is used to excite selectively the chlorine molecule in a Ne buffer gas. Due to the fast relaxation induced by the buffer gas, in the excitation spectrum of the D′→A′ emission at 258 nm, a new progression is observed. It is attributed to the 3 1Σu+ state which is the result of an avoided crossing between the Rydberg state πg→5pπ and the valence state (1441) (σg→σu). It is characterized by Te=83251 cm?1, ωe=783 cm?1, ωexe=29.6 cm?1 and re=1.844 Å. |
