Time dependent density functional theory (TDDFT) is widely used to simulate the excited states of organic and inorganic molecules. We calculate the transition dipole moments (TDM) for a selection of commonly employed exchange-correlation functionals for a test set of 15 molecules and compare them with both linear response CC3 and ADC(3) calculated TDMs, which we use as a benchmark. Contemporary range-separated hybrid functionals perform the best for both direction and magnitude, while "pure" local functionals should be employed with caution.
时间依赖密度泛函理论(TDDFT)被广泛用于模拟有机和无机分子的激发态。我们计算了一组 15 个分子的常用交换相关泛函的跃迁偶极矩(TDM),并将其与线性响应 CC3 和 ADC(3) 计算的 TDM 进行了比较,我们将后者用作基准。对于方向和大小,当代的分段混合泛函表现最好,而“纯”局部泛函则应谨慎使用。
