Attached proton test (APT) spectra acquired with residual coupling (termed RECAPT) can be advantageous in assigning "C NMR spectra of complex natural products. RECAPT was applied to the analysis of the =C NMR spectra of two terpene marine natural products to iUustrate its advantages over APT in situ

β¦ Synopsis
Intensity modulated 31P NMR spectra were obtained using the pulse sequence published by Patt and Shoolery. This attached proton test (APT) technique for signal assignment could be applied to systems with long-range heteronuclear couplings in P- 0-C--H fragments. In a model system derived from the alcoholysis of P,sl0 the six reaction products were assigned to the six signals in the "P NMR spectrum.

Proton-decoupled 31P NMR spectroscopy at 1.5 T of the anterior left ventricular myocardium was used to monitor myocardial phosphate metabolism in asymptomatic patients with hypertrophic cardiomyopathy (HCM, n = 14) and aortic stenosis (AS, n = 12). In addition to the well-known phosphorus signals a
A novel resonator for receiving 31P NMR signals at 1.5 T, which because of its topology has been named a "sectorial resonator," exhibits good radio frequency coupling to the adult human liver. Minimal contamination from nonliver tissue (i.e., muscle) was achieved by the use of depth selective pulses
