Abstract
The free induction decay (FID) in a pulsed NMR experiment is in certain cases modulated by a low frequency beat whose characteristics are determined by the spin system. Selective Fourier transformation of the beat-modulated FID (BMFID) permits separation of the broad peak envelope components and the fine structure without invoking arbitrary convolution functions. The mathematical background of the phenomenon is discussed and applications in C-13 FT NMR are illustrated by showing the determination of long range carbon-hydrogen coupling constants in 2-methyl-2-nitropropane and ethylene glycol, the latter under conditions in which the long range coupling is not discernible in the normally processed FID.
