Abstract

We observed rotationally resolved spectra of A(0$^+$) $\leftarrow$ X(0$^+$) and B(1) $\leftarrow$ X(0$^+$) transition of PbO produced in a flow cell by laser ablation. The transition frequency was calibrated using an ultralow expansion etalon and (4s $^2$S$_{1/2}$ - 5p $^2$P$_{1/2}$) absorption line of K atoms at 405 nm within the error of 3 MHz. We determined the rotational constants for a number of vibrational levels of three isotopic molecules, $^{206}$PbO, $^{207}$PbO, and $^{208}$PbO. The interaction among electronic excited states are generally significant in such heavy molecules, and we found perturbations in specific rotational levels [1]. We discuss the potential energy curves of low electronic excited states of PbO on the basis of the global analysis of observed transitions. \\[1mm] \begin{flushleft} [1] K. Enomoto, A. Fuwa, N.
