dc.description.abstractThe electronic absorption spectrum of the $(0,2), (1,3)$, and (6,9) bands of the $B^{4}\Sigma^{-}_{u}-X^{4}\Sigma^{-}_{g}$ system of $C^{+}_{2}$ was obtained using the velocity modulation technique in conjunction with heterodyne detection. 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
