A comparison of the decomposition of electronically excited nitro-containing molecules with energetic moieties C–NO2, N–NO2, and O–NO2

The Journal of Chemical Physics, 2012
Decomposition of electronically excited nitro-containing molecules with different X–NO2 (X = C, N, O) moieties has been intensively investigated over the past decades; however, their decomposition behavior has not previously been compared and contrasted.

Study of the anomalous NO2 symmetric stretch in p-NO2 aniline

Spectrochimica Acta Part A: Molecular Spectroscopy, 1982
Abstract The anomalous doublet corresponding to the NO2 symmetric stretch in p-NO2 aniline is studied by i.r. spectroscopy in 17 solvents and in the crystal. Deuteration of the amino group collapses the doublet and its nature is assigned to Fermi resonance and not to solute self-association.

Paramagnetic Resonance Study of Production of NO2 and NO2— in Irradiated KNO3

The Journal of Chemical Physics, 1962
Experiments were carried out on pure KNO/sub 3/ and KNO/sub 3/ containing KN/sup 15/O/sub 2/ impurity in order to study the relation between NO/ sub 2/ and NO/sub 2/ in irradiated KNO/sub 3/. The results show that NO/sub 2/ is the source of NO/sub 2/ when KNO/sub 3/ with KNO/sub 2/ impurity is irradiated at 77 deg K, and when pure KNO/sub 3/ is ...

Mechanisms of pulmonary NO2 absorption

Toxicology, 1994
Although NO2-induced cytotoxic responses have been well characterized, the specific mechanisms responsible for initiating toxicity remain equivocal. The inhomogeneous distribution of epithelial injury suggests that differential interactions between NO2 and the lung surfaces may contribute to the extent of regional responses.

SAOZ measurements of NO2 at Aberystwyth

Journal of Environmental Monitoring, 2006
We present in this paper fifteen years' measurements, from March 1991 to September 2005, of stratospheric NO2 vertical columns measured by a SAOZ zenith-sky visible spectrometer. The instrument spent most of its time at Aberystwyth, Wales, with occasional excursions to other locations.

Preparation and Raman spectra of Ca(NO2)2·H2O, Ca(NO2)2 and Mg(NO2)2·H2O

Journal of Inorganic and Nuclear Chemistry, 1980
Abstract The above named salts have been prepared from aqueous solutions of the pure nitrates. Distinct compounds Ca(NO2)2·H2O and Ca(NO2)2 which are free of nitrate impurity have been characterized by their Raman spectra. The hydrated salt appears to contain four crystallographically non-equivalent nitrate groups.

Development of the NO2 Adsorbent for a Low NO2 Concentration Gas

2007
The adsorbent that contains metallic (0 valence) copper as active species for NO 2 adsorption and potassium as a capturing agent of NO 2 is extremely effective to the removal from the low NO 2 concentration gas, but it possesses the weak point that the performance deterioration is accelerated under high humidity condition.

CO and NO2 pollution in a long two-way traffic road tunnel: investigation of NO2/NOx ratio and modelling of NO2 concentration

Journal of Environmental Monitoring, 2001
The CO, NO and NO2 concentrations, visibility and air flow velocity were measured using continuous analysers in a long Norwegian road tunnel (7.5 km) with traffic in both directions in April 1994 and 1995. The traffic density was monitored at the same time.

Uniaxial stress measurements on Rb2PbCu(NO2)6 and K2PbCu(NO2)6

Solid State Communications, 1979
Abstract EPR measurements on crystals of compressed tetragonal Rb2PbCu(NO2)6 and K2PbCu(NO2)6 subjected to uniaxial stress have been carried out at various temperatures. The results indicate that uniaxial stress can reorient the crystal axes in both compounds and that smaller stresses are required for Rb2PbCu(NO2)6 than for K2PbCu(NO2)6 at comparable

NO2 (Untersalpetersäure)

1883
Das Spektrum ist ein Bandenspektrum, es war das erste Absorptionsspektrum eines Gases, welches bekannt wurde. Eine sehr genaue Zeichnung findet sich bei Hasselberg. Bei steigender Temperatur werden die meisten Banden dunkler, andere aber schwacher; so sollen nach Moser 3 Banden bei C verschwinden.
