The purpose of the Subcommittee on Notations and Conventions for Molecular Spectroscopy is to establish and recommend a set of conventions and symbols from those that are in common use in the spectroscopic literature. All of its projects have this objective, with the title showing the scope of a project. The symbols, notations and conventions of this field are very detailed and extensive; they have expanded greatly in the past 2 decades as a result of the extraordinary detail revealed by modern laser spectroscopy. This project will complement the
project on vibration-rotation spectroscopy by considering the many additional features introduced by transitions between different electronic states. The final report of the project will present a consistent set of the symbols, notations and conventions that are in current use in the analysis and use of very-high-resolution spectra of electronic-vibration-rotation transitions. The
subcommittee's international membership includes the leading workers in the field, which ensures that the project will provide a consistent basis for the growing international application of high-resolution spectroscopy to studies of space, the atmosphere, and chemical physics.
