Abstract
Resonant two-photon ionization spectroscopy has been employed in the first spectroscopic investigation of diatomic $AlZn.^{1}$ Several discrete transitions were recorded in the energy region from $18400 cm^{-1}$ to $19100 cm^{-1}$. Rotational and lifetime analyses of these transitions have identified two excited molecular states, the $A \Omega^{\prime} = 0.5$ and the $B ^{2}\Pi_{1/2,3/2}$ states, in addition to the ground $X ^{2}\Pi_{1/2}$ state. Collection of the spectrum under hotter source conditions reveals numerous additional spectroscopic features which can be attributed to vibrational or spin-orbit excited ground state molecules. The following constants are reported: $\begin{array}{ll}X\,^{2}\Pi_{1/2,3/2}&r^{\prime \prime}_{v}=2.6944\, \dot{A}, \Delta G{\prime \prime}_{1/2}=154\,cm^{-1}\\A \Omega^{\prime}=0.5&r^{\prime}_{2}=2.4836 \, \dot{A}\\B\,^{2}\Pi_{1/2}&r^{\prime}_{\epsilon}=2.7599\, \dot{A}, \omega^{\prime}_{\epsilon}=195.4 cm^{-1}, \omega^{\prime}_{\epsilon}x^{\prime}_{\epsilon}=0.8 cm^{-1}\\ B\,^{2}\Pi_{3/2}&r^{\prime}_{\epsilon}=2.7295 \dot{A}, \omega^{\prime}_{\epsilon}=210,4 cm^{-1}, \omega^{\prime}_{\epsilon} X^{\prime}_{\epsilon}=5.2 cm^{-1}.\end{array}$
