ESR Investigation of the Rotational Mobility of Spin Probes in Ethanol Solvent Adsorbed to [beta]-Cyclodextrin
Molecular interactions between spin probe reagents and β-cyclodextrin (β-CyD) in ethanol were investigated on the basis of the rotational correlation time of the spin probes as estimated by the ESR spectrum simulation. The effect of the functional groups of spin probes, possibly hydrogen-bonding int...

Summary: | Molecular interactions between spin probe reagents and β-cyclodextrin (β-CyD) in ethanol were investigated on the basis of the rotational correlation time of the spin probes as estimated by the ESR spectrum simulation. The effect of the functional groups of spin probes, possibly hydrogen-bonding interactions, on the hydroxylated surface of the β-CyD molecule were suggested from the thermodynamic data on the rotational correlation times, which could be combined with the rotational mobilities of spin probes confined in a microscopic liquid phase. |
