[交流] 【讨论】TD-DFT计算电子光谱请教高手,如何回答审稿人问题

The experimental work is supported by by theoretical DFT calculation using Gaussian software.Calculations confirmed stability of determined structure. Authors also calculated UV-Vis spectra by means of TDDFT and conclude that experimentally observed spectrum is in good agreement with calculated one. At this point I do not agree with the claim that calculation agrees well with experiment, but, understandably, more precise calculation (e.g. by means of GW and Bethe Salpeter equation) is too demanding for such large system. Experimentally unobserved peaks in calculated spectra are of the same intensity as observed one, thus natural question is if the calculated oscillator strength is overestimated for the peaks at 449nm and 374nm or the problem is more deep due to some TDDFT deficiency (e.g. HOMO-LUMO gap underestimate) and both peaks positions and also intensities are in question. I would welcome if the authors can comment this point.

这是实验问题,为什么704的锋能识别,别的(628~374)识别不了?
希望你给的表是用作supporting material
计算值很难完全跟实验值重合:容积效应(温度,熵,电子绳子耦合……),DFT本身的问题。你只能强调最强的两个锋算出来了。

We appreciate the reviewer's comments on some calculated but experimentally unresolved peaks (449 and 374). Oscillator strength may be overstimated in the gas phase than in the solution, i.e. we calculated gas phase molecule, which approximately represents solution result. It is known solution will reduce transition intensity. However, the calculations do capture the major transition peaks, which are also oberved experimentally. In this sense we say the calculations agree with experiments well.

似乎含有过渡金属。是什么金属?用的什么泛函?

The gas phase geometry of the  铜  complex  was optimized without any symmetry restriction in the doublet state with the DFT method using the hybrid B3LYP functional of GAUSSIAN-03. The calculation was performed by using the standard 6-31G* basis set for C, H, N, and O atoms, and effective core potentials basis set of LanL2DZ for Cu atom

过度金属的激发能受杂化泛函精确交换项的影响可能会比较大,特别是对开壳层分子。建议用纯GGA如BLYP重算一次激发能,和B3LYP比,看看激发能或HOMO-LUMO gap差多少。
