The scientific focus of CPLT is at the borderline between Physics and Chemistry. It is an interdisciplinary conference which unites scientists from many different fields. From its roots in matrix isolation and condensed phase, it has developed into a forum for the discussion of stimulating topics such as the structure and dynamics of matrix isolated species – including reactive intermediates and unusual molecules – or spectroscopy and reactions in quantum hosts. The field extends naturally to planetary and interstellar chemistry, physical and chemical aspects of cryosynthesis, spectroscopy and dynamics of jet-cooled molecules, and clusters. New developments in both experimental and theoretical aspects of these and related fields will be presented.
