Acidity of nitrous and nitric acids
Inorganic Chemistry, 1988The 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 ...

At the Water's Edge: Nitric Acid as a Weak Acid
Journal of the American Chemical Society, 2007Nitric acid plays a role in many important chemical processes that happen in our environment, often at surfaces where less is known about its reactive behavior. Recent studies have shown that undissociated nitric acid is present on the surface of a nitric acid solution. Using ab initio molecular dynamics simulations, we show that a nitric acid molecule

Humidity, Ice, and Nitric Acid
Science, 2004R. S. Gao et al. report average relative humidity, with respect to ice, of over 130% in the vicinity of low-temperature cirrus clouds and contrails (Reports, “Evidence that nitric acid increases relative humidity in low-temperature cirrus clouds,” 23 Jan., p. [516][1]).

Atomic Energy, 1996
In reprocessing spent nuclear fuel, nitric acid process solutions are tbrmed with different levels of radioactivity (raffinates, re-extracLs, etc.). Usually they arc evaporated down in order to reduce their volume, and the liquor vapors are subjected to rectification distillation in order to regenerate the nitric acid and to obtain a condensate ...

Absorption of nitric oxide in dilute nitric acid
Chemical Engineering & Technology, 1991AbstractThis paper presents laboratory‐scale measurements on the absorption of nitric oxide in dilute nitric acid. The NO concentration in the gas feed varied from 250 to 10 000 ppm. Nitrogen was used as carrier gas. The concentration of nitric acid was between 30 and 60 mass‐%. Temperature during the measurements was set at 25 °C.

Nitric Acid and Nitric Oxide in the Lower Stratosphere
Nature, 1968DURING a balloon flight on December 7, 1967, the infrared solar spectrum in the region from 6.2 µm to 10.0 µm was monitored from 30 km as the Sun set. The spectra obtained during this period revealed the strong enhancement of a previously unidentified absorption feature at 1,325.7 cm−1, and examination indicated that this feature was the Q branch of a ...
