The extreme spectral congestion $(> 20$ lines per $cm^{-1}$) necessitates selective detection of fluorescence produced in the excitation spectrum using a monochromato at a spectral slit width of about $2 cm^{-1}$. The 0-1, 1-2, 2-3, and 0-0 bands have been examined using a single mode tunable laser with Rhodamine 101 dye. Constants for the 0-0 band $(3\sigma$ uncertainties in parentheses), $\nu_{00} = 15716.751(3)$, are presented below: The spin-rotation constant, $\gamma$, which is typically a small parameter, is particularly large in Cal $B^{2} \Sigma ^{+}$ due to the proximity of the $A^{2}\pi$ state. en_US dc.format.extent 86648 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title ROTATIONAL ANALYSIS OF THE $B^{2} \Sigma ^{+}- X^{2} \Sigma^{+}$ BAND SYSTEM OF CaI en_US dc.type article en_US
