The rotationally resolved spectrum shows perturbations, which are attributed to the $2^{2}\Pi_{u}$ state. The mixing between the $B^{4}\Sigma^{-}_{u}$ state and the $2^{2}\Pi_{u}$ state for nearly degenerate levels generated enough intensity borrowing to observe twenty $2^{2}\Pi_{u}\leftarrow X^{4}\Sigma^{-}_{g}$ forbidden transitions. The bands, with their corresponding forbidden transitions, were fit to a model Hamiltonian. Line position measurements, line strength factors, and expectation values for the orbital angular momentum, $\langle \Lambda^{\prime} \rangle$, for the forbidden transitions are reported. Molecular parameters from the global fit of each band, including their corresponding forbidden transitions, are reported. en_US dc.format.extent 257873 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title HIGH-RESOLUTION SPECTROSCOPY OF THE $2^{2}\Pi^{u} \leftarrow X^{4}\Sigma^{-}_{g}$ FORBIDDEN TRANSITIONS OF $C^{+}_{2}$ en_US dc.type article en_US
