Abstract

This paper is concerned with the general problem of the interpretation and analysis of nuclear magnetic resonance spectra of systems in which chemical shift and spin-coupling constants are of the same order of magnitude. Only nuclei of spin 1/2 are considered. Detailed methods are developed for:(a) Two chemically non-equivalent nuclei of the same species (written AB),(b) Three nuclei of the same species, two of which are equivalent (written AB₂),(c) Three nuclei (ABX), two of which are of the same species (AB) and the third (X) is either a different species or has a resonance signal well separated from A and B.Proton resonance spectra of S-guaiazulene, 2,6-lutidine, and 2,3-lutidine are reported and used as examples of the methods of analysis.
