An experimental strategy for determining the extent to which multiply isotopically labeled fragments are incorporated intact into relatively complicated compounds of interest is presented. The NMR methods employed are based on isotope-filtered one-dimensional spectra and difference HSQC spectra incorporating a spin echo designed to report on the presence of a second NMR active isotope at a coupled site. They supplement existing methods for determining the extent of isotopic incorporation at…

1H-Detected, Gradient-Enhanced 15N and 13C NMR Experiments for the Measurement of Small Heteronuclear Coupling Constants and Isotopic Shifts
A suite of 1H-detected, gradient-enhanced experiments is presented for the measurement of small 1H−15N and 13C−15N coupling constants in small organic compounds, where no protons are directly bound
A simple and sensitive experiment for measurement of JCC couplings between backbone carbonyl and methyl carbons in isotopically enriched proteins
TLDR
A simple 2D difference experiment is described that allows quantitative measurement of 13C−13C J coupling between backbone carbonyl and side-chain carbons and indicates that the uncertainty in the derived J couplings is generally less than ca.
Quantitative measurement of small through-hydrogen-bond and ‘through-space’1H-113Cd and1H-199Hg J couplings in metal-substituted rubredoxin fromPyrococcus furiosus
TLDR
The method is based on quantitative analysis of a phase-purged heteronuclear spin-echo difference spectrum, and is demonstrated for measuring 1H-113Cd and1H-199Hg J couplings in metal-substituted rubredoxin from Pyrococcus furiosus.
