Nmr spectra, of alcohols

Bhar and his associates studied carboxylic acids in water (213, 214). As water is added to either pure acetic acid or propionic acid, b decreases steadily except for a curious hump in the curve at 50 percent water by volume. This feature is not evident in the acetic acid-water resonance data given by Gutowsky and Saika (851). Batdorf conducted NMR studies of phenols (148). His results are similar to but less detailed than those shown in Fig. 4-4. Crawford and Foster used the spin echo technique for NMR spectra of alcohols but not specifically with interest in H bonding (460).

Spin decoupling is found in the NMR spectra of alcohols, amines, and carboxylic acids. The signals of OH and NH protons are normally unsplit and broad. 

Chiral liquid crystals consisting of poly-y-benzyl-L-glutamate have been used in various organic solvents to enantiomerically resolve the NMR spectra of alcohols, amines, carboxylic acids, esters, ethers, epoxides, tosylates, halides, and hydrocarbons. Enantiomeric pairs exhibit different ordering properties in the liquid crystal, leading to different...
