✦ Synopsis

The laserexcitation spectrum of the transition X2Z+ -A 'II of Pc'aAr has been investigated using a supersonic espansion of a mixture of sodium vapor and argon gas for production of the molecules_ In comparison to previous investigations the rotational constants of the vibrational levels u" = 2.3 and 4 of the X %+ state could in addition be determined. From our results Be deduce a value of R, = 5.008(5) X lO-'O m for the equilibrium internuclear distance and of De = 41.7(S) cm-' for the well depth of the X 2-+ state.

Resonant two photon ionization (R2PI) technique was used to obtain the excitation spectrum of the Ba 2 molecule. A group of 12 vibrational bands was found in the 740 -764 nm region. As a result of mass selective detection, they were attributed unambiguously to the Ba 2 molecule. By comparison to rec
