Acidities of Nitrous and Nitric Acids
European Journal of Inorganic Chemistry, 2005AbstractThe energies of nitrous and nitric acid and their anions were calculated at the MP2(FC)/6‐311++G(2d,2p) level. Their acidity was related to the acidity of hydroxylamine derivatives using isodesmic reactions. This procedure reveals that the molecules of HNO2 and HNO3 are strongly stabilized (by 119 or 206 kJ·mol–1, respectively) but their anions

ChemInform Abstract: Acidity of Nitrous and Nitric Acids. [PDF]
ChemInform, 1988 The origin of the acidity of nitrous and nitric acids was studied via an analysis of the results of ab initio calculations using the 6-311++G** basis set. The difference in energy between the Z and E conformers of nitrous acid could be reproduced when correction was made for electron correlation, and the gas-phase ionization energies of nitrous and ...

The role of nitric acid in atmospheric new particle formation.
Physical Chemistry, Chemical Physics - PCCP, 2018Nitric acid, an air pollutant with strong acidity and oxidizability, can be found in considerable quantities in the gas and aerosol phase. Understanding the role of nitric acid in atmospheric new particle formation is essential to study the complicated ...

Journal of Molecular Structure: THEOCHEM, 2005
Abstract Three local minima on the potential energy surface of the nitric acid dimer are located by computations using hybrid density functional theory and second-order Moller–Plesset perturbation theory with a number of basis sets. The global minimum is a cyclic C 2 h structure, with a binding energy of 8.4 kcal/mol, in which the monomers are ...

ChemInform Abstract: Acidities of Nitric and Nitrous Acids.
ChemInform, 1988AbstractThe greater acidities of nitric acid and nitrous acid relative to each other and relative to common organic acids are due to the initial‐state charge distribution in the molecules and not to preferential resonance stabilization of negative charge in the anions.

Concentration of Nitric Acid Strongly Influences Chemical Composition of Graphite Oxide.
Chemistry, 2017Graphite oxide is the most widely used precursor for the synthesis of graphene through top-down methods. We demonstrate a significant influence of nitric acid concentration on the structure and composition of the graphite oxide prepared by graphite ...
