The complex beat-modulated boron-11 free induction decay of pentaborane-9 is used as a test of the beat spectrum (BS) method for resolution enhancement in a spin system which contains several coupling constants and multiple chemical shifts. The publi

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 separa

The carbon-13 chemical shifts of alkyl-substituted enols are reported. These species were detected by carbon-13 CIDNP signals arising from the hydroxyl-substituted olefinic carbon. The a-hydroxyl substitution effect is discussed in terms of charge de

Paramagnetic contributions to the NMR chemical shifts for nitrogen and oxygen in nitroalkanes, RN0 2 (R = methyl, ethyl, propyl, isopropyl and t -butyl), and in N0 3 − NO 2 + and NO 2 − have been calculated according to the Pople MO theory of che
