Publisher's Synopsis
This volume of the Enrico Fermi Summer School proceedings is concerned with the chemical physics of atomic and molecular clusters of medium and large size which are defined as clusters too large to yield rotationally resolved spectra. In practice this means from trimers and tetramers up. By limiting the field a separation is made between the study of systems of well-known structures (for which the position of each of their fragments is well known) from systems that, because of their dynamical or ``fluid'' status or because of the too large number of components, have to be studied with methods which are intrinsically more statistic.
