Complete characterization of the constrained geometry bimolecular reaction O(1D) + N2O --> NO + NO by three-dimensional velocity map imaging.

The bimolecular reaction O((1)D) + N(2)O --> NO + NO was photoinitiated in the (N(2)O)(2) dimer at a wavelength of 193 nm and was investigated by three-dimensional (3D) velocity map imaging. State selective 3D momentum vector distributions were monitored and analyzed. For the first time, kinetic energy resolution and stereodynamic information about the reaction under constrained geometry conditions is available.

Laser-induced fluorescence spectroscopy of 14N18O and its application to breath analysis.

Laser-induced fluorescence (LIF) spectroscopy is an efficient tool for the detection of low nitric oxide (NO) concentrations down to the parts per trillion (ppt) range. The isotopic selectivity of this method provides a broad potential of applications. Whereas (14)N(16)O and (15)N(16)O have been described extensively this is not the case for the (14)N(18)O isotopologue.

Non-invasive and isotope-selective laser-induced fluorescence spectroscopy of nitric oxide in exhaled air.

The detection of nitric oxide (NO) is of considerable medical interest. NO is involved in a multitude of mammal physiological processes, and various non-invasive concentration determination methods for NO have been developed during the last few years. Regarding time resolved metabolism behavior the quantitative determination of the (15)N(16)O-isotopologue in combination with (15)N-labeled drugs and amino acids is a central interest of current medical research.

Photodissociation dynamics of SOCl2.

New theoretical and experimental results for the ultraviolet photodissociation dynamics of thionyl chloride (SOCl2) are presented and combined with existing data from a variety of sources in order to provide a unified view of the photodissociation dynamics of SOC12. Time-dependent density functional theory on the basis of the hybrid-type B3LYP functional was employed to calculate vertical excitation energies for the SOCl2 parent molecule up to 6.3 eV.
