Selected, multiplet 13C n.m.r. spectra are obtained for three test samples deriving from petroleum and coal sources, by combining gated spin echo (GASPE) and conventional spin echo 3C n.m.r. procedures. Each selected multiplet spectrum contains resonances due to only one of the following groups: aro

Three H-Coal liquids, ASO, ASB, and VSO, have been characterized by quantitative FT-n.m.r. spectroscopy. FT-parameters were chosen to allow determination of aromatic:aliphatic carbon ratios to within 1% and 2% error of the theoretical and the absolute number of aromatic and aliphatic carbons in a si

## Abstract The ^13^C and ^1^H spectra of a series of aromatic ketones, ethers and keto‐ethers were studied using the lanthanide shift reagent (LSR) Yb(fod)~3~ and the data analyzed using the lanthanide induced shift (LIS) ratio method. Studies were carried out on phenalenone, 6‐methoxyphenalenone,
