Abstract
Since the chemical shift δ of the proton magnetic resonance signal of water can be assumed to be approximately proportional to the degree of hydrogen bonding, xHB, the temperature dependence of the chemical shift is calculated using theoretical values of xHB vs t from various theories of water structure. These theoretical curves of δ are compared to the experimental temperature dependence of the chemical shift. In addition, the chemical shift of water in some alcohol and carboxylic acid solutions is measured and discussed.
