Theoretical calculations have been carried out and experimental dipole moments measured for several pyridinium azolate inner salts; depending on the substituent on the pyridinium ring the compounds are either planar, almost freely rotating molecules, or are hindered with the rings perpendicular to each other, and in all cases the dipole moments are very large (10–18 debyel).
已经进行了理论计算,并测量了几种吡啶鎓吡啶鎓内盐的实验偶极矩。取决于吡啶环上的取代基,化合物要么是平面的,几乎自由旋转的分子,要么受环彼此垂直的阻碍,并且在所有情况下,偶极矩都非常大(10-18 debyel)。
