Rotational and Near-IR Spectra of PbF: Characterization of the Coupled $X_1{}^2{\hat{I}}_{1/2}$ and $X_2{}^2{\hat{I}}_{3/2}$ States

Sean Jackson, Luke Kim, Andreas Biekert +7

Observations of the rotational spectrum of lead monofluoride, PbF, have been extended up to transitions in the \textit{v} = 7 level for ${}^{208}$PbF in the lowest $X_1{}^2{\hat{I}}_{1/2}$…
