High-Resolution Study of the X22Pi3/2 --> X12Pi1/2 Fine Structure Transitions of PbF and PbCl.
The near-infrared emission spectra of the X22Pi3/2 --> X12Pi1/2 fine structure transitions of PbF and PbCl have been investigated by high-resolution Fourier-transform spectrometry. Despite the large fine structure splitting, the bands can be equally well analyzed with Hund's case (a) or case (c) formalisms. Accurate rotational constants for the v = 0 vibrational levels of 208PbF and 208Pb35Cl and hyperfine structure constants for 207PbF have been derived. Copyright 1998 Academic Press.
