Abstract
NaK molecules contained in a heat pipe oven have been excited by various lines of a cw argon ion laser and the resulting $D^{1}\Pi \rightarrow X^{1}\Sigma^{+}$ fluorescence series have been photographed with a 3.4 m $spectrograph.^{1}$ Using the technique of collision-induced $satellites^{2,3}$ the following assignments are made: [FIGURE] In order to obtain the upper and lower states’ molecular constants, all the measured line positions are fit simultaneously to the calculated line position given by the difference between the Dunham expansions for the two states. The vibrational and rotational constants will be $reported.^{1}$J. Toueg, R. N. Zare, and M. M. Hessel, Twenty-Seventh Symposium of Molecular Spectroscopy (Abstract 2) (1972). $^{2}$R. Velasco, Ch.
