Temperature and density dependent solute vibrational relaxation in supercritical fluoroform
Temperatureand density-dependent vibrational relaxation data for the v6 asymmetric stretch of W~CO!6 in supercritical fluoroform ~trifluoromethane, CHF3! are presented and compared to a recent theory of solute vibrational relaxation. The theory, which uses thermodynamic and hydrodynamic conditions of the solvent as input parameters, shows very good agreement in reproducing the temperatureand de...
متن کاملVibrational relaxation in supercritical fluids near the critical point
We present a theory for the temperature and density dependence of the vibrational lifetime T1 and the vibrational line position n of a solute in a supercritical solvent, both close to and far from the critical point. The theory is based on the relation between a classical force correlation function and T1 and n. The force correlation function is determined from density functional theory, and ca...
متن کاملTemperature dependence of solute vibrational relaxation in supercritical fluids: experiment and theory
Ž . Ž . Vibrational lifetime T data for the asymmetric CO stretching mode of W CO in supercritical ethane and carbon 1 6 w x dioxide as a function of temperature at various fixed densities are compared to a recent extended hydrodynamic theory 1 . In ethane at the critical density, as the temperature is raised, T initially becomes longer, reaching a maximum ;70 K above 1 the critical temperature...
متن کاملElectrochemistry in supercritical fluids
A wide range of supercritical fluids (SCFs) have been studied as solvents for electrochemistry with carbon dioxide and hydrofluorocarbons (HFCs) being the most extensively studied. Recent advances have shown that it is possible to get well-resolved voltammetry in SCFs by suitable choice of the conditions and the electrolyte. In this review, we discuss the voltammetry obtained in these systems, ...
متن کاملElectrodeposition from supercritical fluids.
Recent studies have shown that it is possible to electrodeposit a range of materials, such as Cu, Ag and Ge, from various supercritical fluids, including hydrofluorocarbons and mixtures of CO2 with suitable co-solvents. In this perspective we discuss the relatively new field of electrodeposition from supercritical fluids. The perspective focuses on some of the underlying physical chemistry and ...
