title: Study of the 41Piu, 51Piu, 61Piu, and 61Sigmau+ States of K2 by Polarization Labeling Spectroscopy
abstract: The polarization labeling spectroscopy technique is used to study excited singlet ungerade states of K2 in the energy range 26 400-30 200 cm-1 above the bottom of the ground state potential. Three states, 4-6(1)Piu, are characterized by sets of Dunham coefficients. The 6(1)Sigmau+ state with an unusual shape of the potential curve is also partially analyzed. Comparison with theoretical calculations is done. Copyright 1997 Academic Press. Copyright 1997Academic Press
