About the book >.>.> The use of high-resolution IR lasers for spectroscopic detection and charac- terization of trace weakly bound cluster species in low-density jet-cooled environments has led to enormous progress in the study of collision dynamics intermolecular forces and intramolecular energy flow. As a partic- ular focus of this talk direct absorption methods in combination with slit supersonic expansions and crossed molecular beams offer an extremely general tool for probing unimolecular and bimolecular dynamics with full quantum-state resolution. In this lecture results from our laboratory are presented in four areas (1) Near-IR spectroscopic studies of multiple rare- gas cluster species such as Ar-HF and Ar-DF (n= 1 2 3 and 4) are dis- cussed which clucidate the role of pairwise and non-pairwise additive (i.e. multibody) effects on minimum-energy structures ‘solvent’-induced vibra- tional red shifts and Van der Waals intermolecular modes of the clusters. (2) A systematic investigation of vibrational frequencies tunnelling dynamics and predissociation lifetimes for all four intermolecular modes in HF and DF dimers is described which provides demanding tests of potential-energy surfaces for this prototypical hydrogen-bonded complex.
