说明

据报道,在杜伦主体晶体中分离的 2,4,5-三甲基苯甲醛 (TMB) 的偶极矩为 1.65 ± 0.09D(基态和最低单线态之间的差异)和 1.05 ± 0.06D(基态之间的差异) 和三重激发态)。 TMB已被确定为Eryngium foetidum L的叶子提取物中存在的主要挥发性成分之一。基于磷光激发和斯塔克光谱数据,已观察到温度和电场的变化导致偶极矩的变化的化合物。

一般描述

Dipole moments of 2,4,5-trimethylbenzaldehyde (TMB) isolated in a durene host crystal have been reported to be 1.65 ± 0.09D (difference between the ground state and the lowest singlet) and 1.05 ± 0.06D (difference between the ground state and triplet excited states). TMB has been identified as one of the major volatile constituent present in the leave extracts of Eryngium foetidum L. Based on the phosphorescence excitation and Stark spectral data, it has been observed that a change in temperature and electric field causes a change in the dipole moment of the compound.
