Associative detachment (AD) paths for H and CN− in the gas-phase: astrophysical implications

the search for the self in becketts theatre: waiting for godot and endgame

this thesis is based upon the works of samuel beckett. one of the greatest writers of contemporary literature. here, i have tried to focus on one of the main themes in becketts works: the search for the real "me" or the real self, which is not only a problem to be solved for beckett man but also for each of us. i have tried to show becketts techniques in approaching this unattainable goal, base...

Measurement of the associative detachment reaction H − + H → H 2 + e − using a merged - beams method

Reactions and Thermochemistry of Alkyl Ions, Cn H2n+1+ (n=1-8), in the Gas Phase

Our research program focuses on identifying reaction processes important for plasma enhancement of combustion systems. Recommendations for temperature and energy dependencies of key ion-molecule reactions are made based on the laboratory measurements described above. Thermodynamic data such as heat capacity, entropy, and enthalpy are not available as a function of temperature for many of the io...

An Ab initio and chemical shielding tensors calculations for Nucleotide 5’-Monophosphates in the Gas phase

Structural and magnetic properties of purine and pyrimidine nucleotides (CMP, UMP, dTMP, AMP, GMP, IMP) were studied at different levels of ab initio molecular orbital theory. These calculations were performed at the hartree-fock level and density functional B3LYP methods. Geometries were fully optimized by following Cs symmetry restrictions. The standard 6-31G** basis set which includes polari...

Absolute energy - resolved measurements of the H − + H → H 2 + e − associative detachment reaction using a merged - beam apparatus

Using a merged-beam configuration, we have performed absolute measurements for the associative detachment reaction H− + H → H2 + e−. Our energy-resolved measurements for this process remove a long-standing discrepancy between theory and experiment for this fundamental reaction. In particular, we find excellent agreement with theoretical results which previously seemed to be ruled out by earlier...
