  Transfer of methylene from ketene to nitric oxide by photoexcitation of reactant pairs in solid argon below the CH2:C:O dissociation limit

  摘要：

  Chemical reaction has been observed upon excitation of ketene.NO pairs isolated in an argon matrix at 12 K with 380- and 355-nm laser radiation. The reaction product was identified as the iminoxy radical CH2=N-O by FT-IR spectroscopy. The CH2 group transfer occurs at excitation energies below the lowest dissociation barrier of ketene and constitutes the first example of a photochemical carbenoid reaction.

  The photodissociation of the nitromethyl radical, CH2NO2, has been studied using a fast beam photofragment translational spectrometer. In these experiments, a fast beam of mass selected, internally cold nitromethyl radicals is formed via negative ion photodetachment of CH2NO−2 and subsequently dissociated. The recoiling photofragments are detected in coincidence using a microchannel plate detector equipped with a time- and position-sensing anode. Two dissociation product channels are observed at each of three dissociation wavelengths investigated in the range 240–270 nm and are identified as (I) CH2NO2→CH2NO+O and (II) CH2NO2→H2CO+NO. In marked contrast to the ultraviolet photodissociation of CH3NO2, no evidence is found for simple C–N bond fission to give (III) CH2NO2→CH2+NO2. Translational energy and angular distributions were obtained for the two observed channels. The translational energy distribution of channel (I) peaks at only 5–8 kcal/mol, while the distribution for channel (II) peaks at ∼60 kcal/mol. The angular distributions for both channels are largely isotropic. The nature of the electronic excitation and dissociation dynamics are considered at length. The upper state in the electronic transition is assigned to the 1 2B1 state. Results of attempts to model various aspects of the dissociation dynamics as statistical processes on the ground state surface indicate this mechanism is very unlikely. Instead, both dissociation channels are believed to occur primarily on excited state surfaces, and mechanisms for these processes are proposed.
• Production of OH from the collision‐free photodissociation of nitromethane at 266 nm

  Photodissociation of nitromethane, CH3NO2, at 266 nm under collision-free conditions results in the single photon production of electronic ground state OH(X 2Πi). A rotational ‘‘temperature’’ of 1750±50 K describes the rotational distribution of the nascent OH radical. A quantum yield of 0.004±0.001 is determined for the photolytic pathway producing the OH radical. Within experimental uncertainty, no Λ-doublet population preference was observed for OH production from H2O2, HNO3, or CH3NO2 photolysis. If a saturation correction is not utilized apparent Λ-doublet population differences are found. This incorrect saturation compensation may account for previous literature Λ-doublet population ratios, fi/ f′i, that are greater than one.
