Estimation of ground and excited states dipole moments of alpha-hydroxy phenyl hydrazone derivatives: Experimental and quantum chemical methods
(Elsevıer Scıence Bv, 2014)
The ground state (mu(g)) and excited state (mu(e)) dipole moments of the studied alpha-hydroxy phenylhydrazones are determined by using solvatochromism theory which is based on the variation of Stokes shift with solvent's ...
Solvatochromism and intramolecular hydrogen-bonding assisted dipole moment of phenyl 1-hydroxy-2-naphthoate in the ground and excited states
(Elsevıer, 2016)
Absorption and steady state fluorescence spectra of phenyl 1-hydroxy-2-naphthoate (abbreviated as PHN) have been recorded in a series of non-polar, polar protic and polar aprotic solvents at room temperature. The pH effect ...
