The various laser lines excited several $C^{1}\Pi_{u} X^{1}\Sigma_{g}^{-}$ and $2^{1}\Sigma_{u}^{\ast}X^{1}\Sigma_{g}^{-}$ transitions and the resulting fluorescence was assigned to the $2{^{1}}\Sigma_{u}\leftarrow 2{^{1}}\Sigma_{g}, c^{1}\Pi_{u}\leftarrow 1^{1}\Pi_{g}, C^{1}\Pi_{u} - 2^{1}\Sigma_{g}$ and $2^{1}\Sigma_{u}-1^{1}\Pi_{g}$ transitions. None of these transitions have been previously observed and this was the first experimental observation of the $2^{1}\Sigma_{u}$ double minimum'' state. The assignment and analysis of the spectra will be presented for both isotopes and the results will be discussed in relation to ab-initio calculations. Several perturbations were observed and their assignment and analysis will be presented. en_US dc.format.extent 53983 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title EXAMINATION OF SOME NEW SINGLET TRANSITIONS IN $Li_{2}$ en_US dc.type article en_US
