Fluorescence Studies of Excited State Intramolecular Proton Transfer (ESIPT) in Molecules Isolated in Solid Argon: 3-Hydroxyflavone and 2,5-Bis(2-benzoxazolyl)hydroquinone
ĥe fluorescence properties of 3-hydroxyflavone and 2,5-bis(2-benzoxazolyl)hydroquinone have been investigated in solid argon matrices a t 15 K. In both cases dominant emission from the tautomeric form of the molecules is observed. The excitation spectra of this fluorescence a n d a weak fluorescence at shorter wavelength show that the latter is due to molecules with a different ground state, pr...
متن کاملThermodynamic Properties for Argon
An analytical equation of state is applied to calculate the thermodynamic properties for argon. Theequation of state is that of Song and Mason. It is based on a statistical-mechanical perturbation theory ofhard convex bodies and can be written as fifth-order polynomial in the density. There exist three temperaturedependentparameters: the second virial coefficient, an effective molecular volume,...
متن کاملMicroscopic Parameters in the Excited State of Toluene and Some of Its Haloderavatives
The Ultraviolet-visible (UV) spectra of toluene, ortho-bromo and para-bromo toluene in different solvents have been studied. The electric dipole moments and polarizabilities in the molecular excited electronic states were determined. It was found that the electric dipole moments for the excited states (µ*) and the ground states (µ) of these compounds are equal, and the change in dipole moment i...

متن کاملThermodynamics of 3-Phase Equilibrium in Argon Based on a Perfect Solid and a Perfect Liquid (v2)
Three-phase equilibrium in argon was obtained based on the thermodynamics of a perfect solid and a perfect liquid (v2). The equation of state (EOS) for a perfect solid was obtained from our previous study of a pure substance using spherical molecules. The EOS for a perfect liquid is a van der Waals EOS with the Carnahan-Starling repulsion term to explain 3-phase equilibrium. The Lennard-Jones p...
