RECOMMENDATIONS FOR NOMENCLATURE AND SYMBOLISM FOR MASS-SPECTROSCOPY - (INCLUDING AN APPENDIX OF TERMS USED IN VACUUM TECHNOLOGY)

The recommendations contained in this document refer to nomenclature relating to theoretical, technological and experimental aspects of mass spectroscopy, and to the symbolism used when presenting and discussing mass spectral data. In 1974, the Commission on Analytical Nomenclature of IUPAC issued recommendations for nomenclature of mass spectroscopy which are in the form of definitions of some of the terms used in this subject. In 1978 the Commission on Molecular Structure and Spectroscopy updated and extended these recommendations and, in addition, made further recommendations concerning the use of symbols, acronyms, abbreviations and newly invented jargon. Because the subject continues to expand rapidly, a further compilation of defined terms has become necessary, and the opportunity has been taken to incorporate previous relevant recommendations concerning nomenclature and symbolism in order to produce a single comprehensive document. A further set of terms relating to vacuum technology, provided through the generosity of the American Vacuum Society, has been appended. It is therefore intended that this set of recommendations should replace the earlier publications on the subject.
