Estimation of ground and excited-state dipole moments of 1, 2-diazines by solvatochromic method and quantum-chemical calculation

Autor: Shivakumaraiah, S.R. Manohara, Leif Gerward, V. Udaya Kumar

Publikováno v: Journal of Molecular Liquids. 181:97-104

Using the theory of solvatochromism, the difference in the excited-state (μe) and ground-state (μg) dipole moments was determined from Lippert–Mataga, Bakhshiev, Kawski–Chamma–Viallet, and McRae equations for three 1,2-diazines (pyrrolo-pyrid
