Abstract

An electronic spectrum is observed for the new heteronuclear metal dimer, AgK. Two electronic states are observed with origins near 315 nm. Spectra are detected for three isotopomers with mass-resolved one-color two-photon photoionization spectroscopy (R2PI). The vibrational bands in the more intense state (ωe = 85.8 cm-1) have rotational structure consistent with a 1Σ+1Π transition. This structure is red-shaded, consistent with an excited state having a significantly longer bond (3.02 Å) than the ground state (2.40 Å). The possible importance of ionic bonding is discussed.
