The infrared spectrum of the water dimer trapped in solid neon has been recorded up to the visible by improving significantly the experimental technique used in a previous paper [Y. Bouteiller, J.P. Perchard, Chem. Phys. 305 (2004) 1]. A total of 22 intramolecular transitions of the proton donor (PD) and 23 of the proton acceptor (PA) are now identified and assigned on the basis of 16O/18O isotopic shifts and of realistic anharmonicity corrections. From an ab initio determination of the potential energy a perturbation-resonance treatment has been carried out for each polyad Pn, n = 2–8. Finally combinations of intra + intermolecular transitions were identified and assigned on the basis of calculated anharmonicity coefficients.
Chemical Physics publishes experimental and theoretical papers on all aspects of chemical physics. In this journal, experiments are related to theory, and in turn theoretical papers are related to present or future experiments. Subjects covered include: spectroscopy and molecular structure, interacting systems, relaxation phenomena, biological systems, materials, fundamental problems in molecular reactivity, molecular quantum theory and statistical mechanics. Computational chemistry studies of routine character are not appropriate for this journal. In addition to regular research papers, Chemical Physics publishes invited perspectives articles (called ChemPhys Perspectives) and Special Thematic Issues. Each Chemical Physics Special Issue provides a snapshot of the leading edge in current research of a particular field in chemical physics, and contains invited articles by specialists in that field. While they are not meant to be reviews as such, the Special Issues should provide easy access to the relevant literature. The objective is to create a collection of articles representative of the newest findings in a field and equivalent to that covered at a topical conference. Guest editors or their designates are encouraged to write a ChemPhys Perspective on the subject of their Special Issue.
