NOTATIONS AND CONVENTIONS IN MOLECULAR-SPECTROSCOPY .1. GENERAL SPECTROSCOPIC NOTATION

The field of Molecular Spectroscopy was surveyed in order to determine a set of conventions and symbols which are in common use in the spect roscopic literature. This document, which is Part 1 in a series, estab lishes the notations and conventions used for general spectroscopic no tations and deals with quantum mechanics, quantum numbers (vibrational states, angular momentum and energy levels), spectroscopic transition s, and miscellaneous notations (e.g. spectroscopic terms). Further par ts will follow, dealing inter alia with symmetry, notation, permutatio n and permutation-inversion symmetry notation, vibration-rotation spec troscopy and electronic spectroscopic.
