Two newly synthesized alkylated cyanomalonaldehyde derivatives possess very short intramolecular hydrogen bonds, which are studied by deuterium NMR. Both the dimethyl and di-tert-butyl derivatives have small deuterium quadrupole coupling constants and large asymmetry parameters. In addition, the di-
Some of the important combustion properties of deuterium such as flammability limits, laminar burning velocities, and detonation cell widths have been determined experimentally. The experiments provide a basis for evaluating the properties of deuterium-air or deuterium-oxygen-diluent mixtures from t
Proton (deuteron) transfer ofhydrogen bonds in benzoic, glutark and pformylbenzoic acids was studied by proton (deuteron) T, measurements. Deuteration of carboxylic protons was found to increase the barriers to classical proton jumping as well as quantum-mechanical tunneling. The former barriers inc
