Dissociative properties of 1,1,1,2-tetrafluoroethane obtained by computational chemistry
Japanese Journal of Applied Physics, 2018Abstract The electronic properties and dissociative channels of the alternative to the CCl 2 F 2 (CFC-12) refrigerant, 1,1,1,2-tetrafluoroethane (HFC-134a) with a low global warming potential (GWP, 1430), were revealed by computational

Dissociative Recombination Chemistry and Plasma Dynamics
2008Abstract : Advances made in the study of the dissociation dynamics and product branching ratios of energized transient neutral molecules formed by charge-transfer (DCE) and recombination of cations with free electrons (DR) are reviewed. The results obtained include detailed measurements of the three-body dissociation of H3, O4 and sym-triazine (HCN)3 ...

European Journal of Mass Spectrometry, 2008
The collision induced dissociation and electron induced dissociation spectra of the [2M + H] + and [2M + Na] + clusters of the zwitterionic amino acid, betaine (M), have been examined in a hybrid linear ion trap Fourier transform ion cyclotron resonance

Dissociative chemistry of ionic transition metal cluster fragments
Journal of Cluster Science, 1991The ionic fragments formed by collision-induced dissociation of Mn2(CO) + ions (y=1–10) are reported. The ratio of product ions formed by metal-metal vs. metal-ligand bond cleavage are discussed in terms of the dependence of the metal-metal bond energy on the ...

Molecular ion collision chemistry in CH4 ionization and dissociation
International Journal of Mass Spectrometry, 2016Abstract The use of the 90° hemispheric electrostatic high resolution analyzer in conjunction with the time-of-flight (TOF) technique allowed us to identify various species associated with the ionization of methane molecular gas by a pulsed fast 19 MeV F4+ beam.

Use of hydration and dissociation chemistries with the electrolyte–NRTL model
AIChE Journal, 1999AbstractSound theoretical understanding and accurate mathematical representation of electrolyte solution nonideality were the subject of extensive research efforts for decades. It is demonstrated that these goals can be achieved by incorporation of hydration and partial dissociation chemistries with the semi‐empirical electrolyte NRTL model.

Dissociation Processes in Plasma Chemistry and Gaseous Dielectrics
1991Plasma processing is widely used in integrated circuit manufacturing. In a typical plasma process a chemically nonreactive feed gas flows into a discharge reactor where the discharge electrons dissociate the feed gas and produce chemically reactive products.

Excited-State Acid−Base Chemistry: Evidence for a Dissociative Excited State
Inorganic Chemistry, 2003Excitation (410 nm) of the bimetallic [(bpy)(2)Ru(CN)(mu-CN)Rh(NH(3))(4)Br](2+) produces the MLCT state localized on the (bpy)(2)Ru(CN)(2) ligand. Photoinduced cleavage of the bimetallic occurs in the presence of [H(+)], and the dependence yields a K(a) equivalent to that for ground-state cis-(bpy)(2)Ru(CN)(2) implying separation of the bimetallic ...

Band spectra and dissociation energies: A physical chemistry experiment
Journal of Chemical Education, 1962An experiment that has proved successful in introducing the spectroscopic determination of molecular energy levels and thermodynamic quantities is the analysis of the visible band spectrum of either iodine or bromine. In addition, this experiment introduces techniques now widely used in high temperature and astro-chemical studies.
