Hydrogen bonds play critical roles in protein structure, stability, and function. Conventionally, hydrogen bonds are mainly determined by X-ray crystallography and NOE-based NMR spectroscopy in indirect manners. In recent years, it was demonstrated t

Rate data for the hydrolysis of isopropyl bromide in deuterium oxide are determined over a temperature of 35 to 80 deg . By comparison with earlier data for hydrolysis in water, it was shown that the solvent isotope effect (k/sub D// sub 2//sub O// k

The Gross-Butler theory for the solvent isotope effect of deuterium on acid-catalyzed reaction rates in thermodynamic activity function, Q' (n), for proton and deuteron at 25 deg are derived from experimental data by using the correct value for the i

Deuterium gas exchanges slowly with liquid methanol over Raney nickel catalyst at 35 deg . The reaction is zero order with respect to deuterium pressure and has a low activation energy. The influences of catalyst weight, catalyst treatment, and of th
