We report the first observation of sum frequency generation (SFG) photons on high-surface-area powders, critically important materials in heterogeneous catalysis. We utilize SFG in total internal reflection (TIR) geometry and show that the TIR-SFG ap

We have extended two previously introduced models of n‐alkanes to numerically investigate the liquid‐state dynamics of branched alkanes. We compare our results with new experimental measurements of diffusion and 13C‐NMR T1 relaxation. Significa

1 H and 2 H NMR line-shape studies have been used to investigate the low-temperature phase behavior of pyridine-d 5 and N-methylpyrrolidinone-d 9 (NMP) swollen-Pittsburgh No. 8 coal, Illinois No. 6 coal, and Zap lignite. Good solvents like pyridine a

1 H NMR relaxation techniques were used to study the mobility of coals swollen with pyridine-d 5 and N-methyl-2-pyrrolidinone-d 9 (NMP) as a function of solvent loading at room temperature. A spin-echo technique was found to give better results than

The solid residues from pyridine Soxhlet extraction of Pocahontas No. 3, Upper Freeport, Pittsburgh No. 8, Illinois No. 6, and Wyodak coals were exposed to 4-vinylpyridine vapors and swelled. All of the 4-vinylpyridine could not be removed under vacu

Solvent-induced association of high-volatile bituminous coal and its extracts is observed on soaking in organic solvents and results in a decrease in pyridine extractability. Medium- and low-volatile bituminous coals dissociate with the same treatmen
