## Abstract The use of common, that is nondeuterated, ionic liquids for NMR spectroscopic purposes as the only solvent causes large signals arising from solvent resonances. Ionic liquids (ILs) with long side chains possess signals throughout the spectral range of protons, thus rendering simple solv
## Abstract Improved methods for the assignment of resonance multiplicity in ^13^C NMR spectra are described. Assignments are achieved either by direct observation of resonance intensity modulations resulting from gated spin echo (GASPE) experiments, or from the derivation of โselected multipletโ s
## Abstract In this communication, we describe the design of an online multiโchromatographic approach to the routine NMR analyses of lowโlevel components (โผ0.1%) in complex mixtures. The technique, termed LC^2^โSPEโNMR, optimally combines multiโdimensional liquid chromatography with SPE technology
COSY and NOESY spectra (400 MHz) have been used to complete the assignment of the 'H NMR spectra of 1and 3-nitrobenzo[e]pyrene. Both compounds show strong bay region nuclear Overhauser enhancement and significant coupling across bay regions. Both compounds also exhibit extensive long-range couplings
