The ground state and excited state dipole moment of a series of alkyl substituted para-nitroaniline derivatives is reported. Ground state dipole moment was determined by the Debye-Guggenheim method and the excited state dipole moment was estimated using the solvatochromic method. For all molecules under investigation, the excited state dipole moment was found to be higher than the ground state dipole moment. The molecules exhibited positive solvatochromism.
报道了一系列烷基取代对硝基苯胺衍生物的基态和激发态偶极矩。基态偶极矩通过德拜-古根海姆方法测定,激发态偶极矩使用溶剂化显色法估算。对于所有研究的分子,发现激发态偶极矩高于基态偶极矩。这些分子表现出正溶剂化显色现象。
