Experimental investigation of CO2 valorization by plasma discharges
… can be exploited to channel energy in the molecular dissociation rather than in heating the gas, allowing endothermic reactions to take place at relatively low temperatures. One of the main studied processes is CO2 reduction, which enable recycling this greenhouse gas, producing CO, an …

Vibrational Spectroscopy and Potential Energy Surface Analysis of the X˜ And B˜ States of Thiophosgene
… modes, and extend in energy beyond the lowest molecular dissociation threshold. A full six-dimensional potential energy surface transformed to a normal coordinate representation has been fit to the experimental X˜(1 A1) levels up to 8,000 cm-1. A six-dimensional multi-reference PES has …

Study of Wavepacket Dynamics in Rubidium Vapor by Means of Time-Frequency Analysis
… dynamics suggest that not only atomic but also molecular ( Rb*2 ) wavepackets are generated, and that the temporal history of the amplitude of the quantum beats reflects the production of the excited atomic fragments of Rb*2 dissociation. More precisely, changes in the Rb excited state number …

Quantum Monte Carlo studies of dense hydrogen and two-dimensional Bose liquids
… the regime of cooperative thermal and pressure dissociation, relevant to structural models of the giant planets' interiors. We treat the protons and electrons as quantum particles, thereby avoiding the Born-Oppenheimer approximation. Fermi-Dirac exchange statistics are treated within the …

Ultrasound induced cavitation and sonochemical effects
… are generated. Under such extreme conditions molecular dissociation occurs and produces highly reactive free radicals. This phenomenon provides a means of "burning" substances in liquids and enhancing reactions that cannot be achieved by conventional means. Sonochemistry, the chemistry …

Forced oscillations in simple and binary gas atmospheric models
… diffusing gas atmosphere. This model excludes molecular dissociation and ionization in the upper regions and absorption of solar energy. Incorporation of all these properties would render the problem impossibly difficult . As a first step to the development of the analysis for the complex …

Molecular vibrational diagnostics - from quantum state stability to real time histopathology
… to behave more statistically with increasing molecular size. We show that the size-invariance of the mean vibrational frequency and the molecular dissociation energy conspire to create a stable set of non-statistical quantum states that grows with molecular size. We derive a scaling relation …

Following a Photochemical Reaction of Br2 using Photoion and Photoelectron Momentum Spectroscopy
… model for simulating both atomic and molecular photoelectron spectra.. For atomic ionization, various of interference structures are comprehensively studied. In particular, we investigate the origin of fan-like interference structure by employing a time-variable soft-core Coulomb …

Attosecond Wave Packet Metrology
… molecules to attosecond pulses can trigger dissociation reactions that can be controlled by a delayed probe laser pulse. We present a study of different probe pulse properties and report the observation of attosecond electron dynamics inside a hydrogen molecule.
