WebPhotodissociation dynamics of NO2 in its conical intersection region have been explored experimentally on a real-time scale by time-of-flight mass spectrometry. Excited at 400.6 … WebApr 13, 2024 · Time-resolved photoionization measurements were performed on o-nitrophenol pumped with UV laser pulses at a central wavelength of 255 nm (4.9 eV) and probed with vacuum ultraviolet (VUV) pulses at 153 nm (8.1 eV).The photoelectron spectrum and time of flight mass spectrum for ions were recorded at each pump–probe delay.
The photodissociation of NO2 by visible and ultraviolet light
WebWe employ ultrafast mid-infrared transient absorption spectroscopy to probe the rapid loss of carbonyl ligands from gas-phase nickel tetracarbonyl following ultraviolet photoexcitation at 261 nm. Here, nickel tetracarbonyl undergoes prompt WebMar 21, 2002 · [1] This paper describes a new instrument that uses a combination of thermal dissociation and laser-induced fluorescence detection of NO 2 for in situ detection of the sum total peroxy nitrates, the sum total of alkyl nitrates and hydroxyalkyl nitrates, and HNO 3.The instrument is capable of routine, continuous in situ measurements of these three … flagstaff to grand canyon driving
PHOTODISSOCIATION OF NO2 BY PULSED LASER LIGHT AT …
WebThe results of studies of the photodissociation of a NO 2 molecule in the ultraviolet wavelength range were considered in [28,29]. It was shown that the distribution of NO fragments over vibrational states during fragmentation of the NO 2 molecule is inverted. The population of vibrational levels is significant up to the value of the ... Photodissociation, photolysis, photodecomposition, or photofragmentation is a chemical reaction in which molecules of a chemical compound are broken down by photons. It is defined as the interaction of one or more photons with one target molecule. Photodissociation is not limited to visible light. Any … See more Photolysis is part of the light-dependent reaction or light phase or photochemical phase or Hill reaction of photosynthesis. The general reaction of photosynthetic photolysis can be given in terms of photons See more In astrophysics, photodissociation is one of the major processes through which molecules are broken down (but new molecules are being … See more Currently orbiting satellites detect an average of about one gamma-ray burst per day. Because gamma-ray bursts are visible to distances encompassing most of the observable universe, … See more • Flash photolysis • Photocatalysis • Photochemistry • Photohydrogen See more Photoacids are molecules that upon light absorption undergo a proton transfer to form the photobase. In these reactions … See more Photolysis occurs in the atmosphere as part of a series of reactions by which primary pollutants such as hydrocarbons and nitrogen oxides react to form secondary pollutants such as peroxyacyl nitrates. See Photochemical smog. The two most … See more Single photons in the infrared spectral range usually are not energetic enough for direct photodissociation of molecules. However, after absorption of multiple infrared photons a molecule may gain internal energy to overcome its barrier for dissociation. … See more WebDec 15, 1992 · Multiconfigurational time-dependent Hartree study of complex dynamics: Photodissociation of NO2.
