A test case for time-dependent density functional theory calculations of electronic circular dichroism:2-chloro-4-methoxy-6-[(R)-1-phenylethylamino]-1,3,5-triazine

摘要

The three-dimensional structure of an optically active substituted s-triazine derivative,2-chloro-4-methoxy-6-[(R)-1-phenylethylamino]-1,3,5-triazine,has been studied by conformational analysis using density functional theory (DFT) both in vacuo and in acetoni-trile solution in the polarizable continuum model integral equation formalism framework.Time-dependent DFT methods have been used to investigate the molecular electronic CD and absorption UV spectra.Comparison with experimental results allowed the reliability of the theoretical predictions to be enhanced and suggested a possible interpretation of the measured data.
