Rotational dynamics of 3-(benzo[d]thiazol-2-yl)-7-(diethylamino)-2H-chromen-2-one (3BT7D2H-one) non-polar solute in non-polar solvents has been studied by varying temperature to find out how hydrodynamic friction is influenced by solute-size ratio. It has been observed that the rotational dynamics of 3BT7D2H-one follow the Stoke's-Einstein-Debye (SED) model in an n-hexane solvent and it follows the Gierer and Wirtz (GW) model in an n-decane solvent. The probable reason is due to the solute-solvent size ratio which influences boundary conditions parameters and consequently on rotational dynamics of solute.
通过改变温度，研究了3-(苯并[d]噻唑-2-基)-7-(二乙氨基)-2H-色烯-2-酮（3BT7D2H-酮）非极性溶质在非极性溶剂中的旋转动力学，以探究流体动力学摩擦如何受溶质-尺寸比的影响。据观察，3BT7D2H-酮在正己烷溶剂中的旋转动力学遵循斯托克斯-爱因斯坦-德拜（SED）模型，而在正癸烷溶剂中则遵循吉勒尔和维尔茨（GW）模型。可能的原因是溶质-溶剂尺寸比影响了边界条件参数，进而影响了溶质的旋转动力学。
