✦ Synopsis
Laser-induced fluokcence of Csz molecuks. recorded by high-rescktian Fourier spectroscopy, has been used for the fist spectroscopic identification of the lowest gerade triplet (1) '2: electronic state. This state can be described by tbe molecular parameters: -T, = 11602.10 cm-?, B, = 8.23 X 10m3 cm-', D,= 2.56 X 10m9 cm-' and R, -55425 44. Detern,ination of the absolute vibrational numbering will require further experiments.

We report the observation of a band system between 510 and 540 nm in laser induced fluorescence spectra of Cs2 excited by the Ar + laser lines Aexc = 488 nm, Aexc = 496.5 nm and A~xc = 501.7 nm. Using potential energy curves of Cs2 and performing quantum mechanical simulations of the spectra we assi
