Photodissociation of dimethylnitrosamine
Chemical Physics Letters, 1981Abstract Photodissociation of (CH 3 ) 2 N-NO following S 1 (nπ * ) ← S 0 excitation yields (CH 3 ) 2 N − and NO with a quantum yield of 1.03 ± 0.10. These fragments recombine leaving no stable photopioducts. A fraction of NO produced by photolysis is vibrationally excited.

The photodissociation of SO2+·
International Journal of Mass Spectrometry and Ion Processes, 1985Abstract The first ion photodissociation study of SO2+· is reported. Unlike CH3I+· which photodissociates from the molecular ion ground state, SO2+· is observed to photopredissociate from the A and B states via the C and D states. The C ← B contribution to the low energy region is assigned and vibrational frequencies of 100, 46.5 and 55.5 meV are ...

Transition moments and energies have been calculated for the X-A, bound to continuum, transition in HgCl. The photodissociation cross section at the peak (∼20 000 cm−1 or 500 nm) is 1.2×10−18 cm2 at 600 K. The laser energy 17 921 cm−1 or 558 nm) for the B-X transition is close to the peak energy, and a significant absorption will result from a buildup ...

The photodissociation of the SiO molecule, which is of considerable astrophysical interest, is studied within the framework of the Floquet theory. Only the one-photon transition process between the two lowest EΣ+1 states is considered. The computation of the electronic energy surfaces is performed with the MOLPRO code.

Photodissociation of NO+(NO) and NO+(H2O)
The Journal of Chemical Physics, 1977A drift tube mass spectrometer coupled with ion laser and ion laser pumped tunable dye laser photon sources has been used to measure the thermal energy (300 K) photodissociation cross sections for two positive ion clusters, NO+(NO) and NO+(H2O). Measurements were made spanning a photon wavelength range from 799 to 350 nm. The absolute photodissociation

The Journal of Chemical Physics, 1969
A valence-bond calculation is carried out on the ground and six excited energy levels of methane. The molecule is deformed in a C2v fashion so as to produce incipiently CH2 and H2, and in a C3v fashion to obtain CH3 and H. Potential surfaces are obtained which permit one with classical mechanics to determine the shape of the molecule during its ...

Photodissociation of thiophosgene
The Journal of Chemical Physics, 1977The photolysis of thiophosgene produces CS(A 1π) below the incident wavelength (1270 Å) from which ΔHf °0(SCCl2) ?7.92±1 kcal mol−1 (33.1±4 kJ mol−1) is derived. The quantum yield for the production of Cl atoms has been determined from the amounts of HCl produced from the photolysis of thiophosgene–heptane mixtures.

Photodissociation of Triarylmethanes
1984Recently there have appeared several reports of picosecond absorption studies for the photodissociation of triarylmethanes(1,2,3). This class of molecules is of interest as photoexcitation leads to the formation of ion pairs, the kinetics of which are highly solvent dependent.
