Enter a chemical formula to calculate its molar mass and elemental composition: Molar mass of HO2NO is 63.0128 g/mol

Hydrogen oxides (HOx D HO2C OH) and nitrogen oxides (NOx D NO2C NO) play central roles in atmospheric pho-tochemistry. HO2, a product of OH-initiated volatile organic compound (VOC) oxidation, reacts with NO to produce NO2, a key step in the photochemical ozone formation cycle in the troposphere.

HONO, like NO2, has strong absorption in visible and a highly structured spectrum. Its photochemical lifetime in the atmosphere is ~ a few minutes. 0.35 at 248 nm; more measurements needed! Unique in that it can be broken by near-infrared radiation.

Q(300.0)= 83943.9398 Q(225.0)= 54498.4726 Q(150.0)= 29653.6339 Q(75.00)= 10484.3770 Q(37.50)= 3710.2733 Q(18.75)= 1314.8390 Q(9.375)= 467.1471

We infer the sum of HO2NO2 and CH3O2NO2 as the difference between 6PN measurements and gas chromatographic measurements of the two major peroxy acyl nitrates, peroxy acetyl nitrate (PAN) and peroxy propionyl nitrate (PPN).

290 nm. Graham et al. prepared H02N02 vapor in a static system at a con-centration of a few millitorr, and their cross section values are

Consequently, at lower and mid latitudes HO2NO is only expected to build up to significant concentrations in the upper troposphere, whereas photolysis and reaction with OH are expected to be the dominant loss processes.

Peroxynitric acid (HO2NO 2) is predicted by pho- blended lines. One digit beyond the estimated . tochemical models to be an important reservoir gas accuracy of each position has been retained. The in the lower stratosphere where it is believed to …

Mar 4, 2022 · Band strengths for the second (3νOH) and third (4νOH) overtones of the OH stretch vibration of peroxynitric acid, HO2NO2 (PNA) in the gas-phase were measured using Cavity Ring-Down Spectroscopy (CRDS). Both OH overtone transitions show diffuse smoothly varying symmetrical absorption profiles without observable rotational structure. Integrated band strengths (base e) at 296 K were determined ...
