Rotational correlation time : ウィキペディア英語版 | Rotational correlation time Rotational correlation time is the time it takes for a molecule to rotate one radian, on average. Rotational correlation times are in the order of picoseconds, for example 1.7 picoseconds for water〔10.1002/bbpc.19820860308〕 or in the tens to hundreds range for small organic molecules.〔For a molecule of 184 g/mol in a solvent, see 10.3891/acta.chem.scand.29a-0089〕 Rotational correlation times are employed in the measurement of microviscosity (viscosity at the molecular level) and in protein characterization. Rotational correlation times may be measured by rotational (microwave) or dielectric spectroscopy. Rotational correlation times of probe molecules in media have been measured by fluorescence lifetime or for radicals, from the linewidths of electron spin resonances. == References ==
