Vectorial Imaging of the Photodissociation of 2-Bromobutane Oriented via Hexapolar State Selection
Masaaki Nakamura, Po-Yu Tsai, Shiun-Jr Yang +6
Molecular orientation techniques are becoming available in the study of elementary chemical processes, in order to highlight those structural and dynamical properties that would be…
Quadrilaterals on the square screen of their diagonals: Regge symmetries of quantum-mechanical spin-networks and Grashof classical mechanisms of four-bar linkages
Vincenzo Aquilanti, Ana Carla Peixoto Bitencourt, Concetta Caglioti +4
The four-bar linkage is a basic arrangement of mechanical engineering and represents the simplest movable system formed by a closed sequence of bar-shaped bodies. Although the mech…
Nucleophilic substitution vs elimination reaction of bisulfide ions with substituted methanes: exploration of chiral selectivity by stereodirectional first-principles dynamics and transition state theory
Marcos Vinicius C. S. Rezende, Nayara D. Coutinho, Federico Palazzetti +2
Control of molecular orientation is emerging as crucial for the characterization of the stereodynamics of kinetics processes beyond structural stereochemistry. The special role pla…
Stereodynamics Imaging of Bromine Atomic Photofragments Eliminated from 1-Bromo-2-methylbutane Oriented via Hexapole State Selector
Masaaki Nakamura, Hsiu-Pu Chang, King-Chuen Lin +4
Both single-laser and two-laser experiments were conducted to look into the ion-imaging of Br*(2P1/2) and Br(2P3/2) photo-fragmented from 1-bromo-2-methylbutane in the range 232-24…
A Quantum Chemical Approach for the Characterization of the Interaction Potential of Propylene Oxide with Rare-Gas Atoms (He, Ne, Ar)
Patricia R. P. Barreto, Ana Claudia P. S. Cruz, Henrique O. Euclides +3
Propylene oxide is one of the simplest organic chiral molecules and has attracted considerable interest from the scientific community a few years ago, when it was discovered in the…
Spherical and hyperspherical harmonics representation of van der Waals aggregates
Andrea Lombardi, Federico Palazzetti, Vincenzo Aquilanti +4
The representation of the potential energy surfaces of atom molecule or molecular dimers interactions should account faithfully for the symmetry properties of the systems, preservi…
