Polarization labelling spectroscopy is applied to study excited states of K2 lying in the energy range 23800-25800 cm-' above the bottom of the ground state. The two observed states are identified as 3 'l&(4 'S+S 'P) and 3 '&/ (4 \*S+ 3 'D). Molecular constants are derived for both states from a Dun

✦ Synopsis
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 assign these new structures to the transition 3 lEu+ ---* 1 l~g.
