The analysis of complex nuclear magnetic resonance spectra

Abstract

The theoretical scheme described in Part I for the analysis of nuclear resonance spectra of the type ABX _q is extended to systems AB₂X _q where the symmetry is such that there is only one BX coupling constant. It is shown that these spectra can be interpreted in a systematic manner for all q. The spectra allow determination of the relative signs of all three coupling constants and can therefore be used to compare couplings between nuclei of different species (AX and BX) with the coupling between nuclei of the same species (AB). Further systems which could be studied by similar methods are indicated briefly.
