Abstract

Simple equations that deal with the effect of spin-spin interactions on transition intensities, and with some effects on spin populations, were combined to give an estimate of transition intensities for AX, AX 2, and AX 3 systems. Here A was 13C and was the observed nucleus, and X was protons continuously influenced by a suitable radio-frequency magnetic field. Calculation parameters were chosen to compare with published calculations of spin-spin interactions in the absence of Overhauser effects. Calculated results were compared to data obtained with formic acid, methylene bromide, and methyl iodide.
