Abstract
\begin{wrapfigure}{l}{0pt} \includegraphics[scale=0.11]{figure1.eps} \end{wrapfigure} The optical spectra of the diatomic PdS radical in the gas phase have been investigated for the first time through a combination of laser-induced fluorescence (LIF) and single vibronic level emission spectroscopy. The [22.3] $^3\Sigma^-$ $-$ $X$ $^3\Sigma^-$ transition system containing sixteen vibrational bands was identified in the LIF spectra in the energy range of 22,030 $-$ 23,400 cm$^{-1}$. Rotationally resolved spectra and analysis enabled a determination of the molecular structures in the upper and lower states, involving the rotational constants, the vibrational constants, the spin-orbit splittings, and the vibrational isotope shifts. The emission transitions from the [22.3] state down to the ground state and to the low-lying $A$ $^3\Pi$ state were recorded, by which the spin-orbit splittings of $A$ $^3\Pi_{2,1,0^{-,+}}$ were determined. A comparison of the bond lengths (and the vibrational frequencies) of the VIII group monosulfide radicals (NiS/PdS/PtS) reveals the relativistic effects in the Pd and Pt atoms.
