摘要：

An electronic spectrum is observed for the new heteronuclear metal dimer, LiAl. This dimer is produced by laser vaporization of an alloy metal sample in a pulsed nozzle cluster source. Resonant two-photon photoionization (R2PI) is employed to collect this spectrum. We observe and characterize two excited electronic states for both the Li-6-Al and Li-7-Al isotopes. The analysis of hotbands provides the vibrational frequency (318.3 cm(-1)) and dissociation energy (0.75 eV) for the LiAl ground state, which both agree well with the predictions of ab initio theory.
