Mass-analyzed threshold ionization (MATI) spectroscopy is applied for the first time to a metal van der Waals complex, AlAr. The experimental configuration for MATI uses a time-of-flight mass spectrometer, oriented perpendicular to the molecular beam axis, without modification of any components. The vibrationally resolved spectrum yields a frequency of ω″e=67 cm-1 for the ground state of Al+Ar, and a value of ΔG″ 1 2=39 cm-1 for neutral AlAr.
