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 r elating to theoretical, technological and experimental aspects of mass spectroscopy, and to the symbolism used when presenting and discussin g mass spectral data. In 1974, the Commission on Analytical Nomenclatu re of IUPAC issued recommendations for nomenclature of mass spectrosco py which are in the form of definitions of some of the terms used in t his subject. In 1978 the Commission on Molecular Structure and Spectro scopy updated and extended these recommendations and, in addition, mad e further recommendations concerning the use of symbols, acronyms, abb reviations and newly invented jargon. Because the subject continues to expand rapidly, a further compilation of defined terms has become nec essary, and the opportunity has been taken to incorporate previous rel evant recommendations concerning nomenclature and symbolism in order t o produce a single comprehensive document. A further set of terms rela ting to vacuum technology, provided through the generosity of the Amer ican Vacuum Society, has been appended. It is therefore intended that this set of recommendations should replace the earlier publications on the subject.
