✦ Synopsis

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 Dunham expansion.
