在完整的审稿意见中没有提到簇模型(cluster model),所以我觉得很难理解。我认为簇模型最贴近他的建议的内涵,而且固定周围片段后分别优化中心分子的基态和激发态构型应该是很合理的。如果他的意思真的是簇模型,那单纯说优化氢原子的结构真的意义不明,尤其是后面提到可以模拟弛豫过程。审稿意见的原文后续部分为“ Therefore, the authors can check whether the electronic energy levels obtained from the fully relaxed gas-phase optimization correlate to the hydrogen-optimized electronic energy levels during TDDFT calculation on the ground state structure. If not, then the discussion based on the Jablonski diagram of the fully optimized structures cannot demonstrate the photophysical phenomenon. It may adversely affect the claim on the TSDP behavior due to poor modeling in the computational part. The authors claimed that in the solid state, the relaxation pathways of the excited states may differ due to restricted molecular motion and enhanced non-radiative processes, further contributing to the observed differences. The non-radiative processes can be captured well if a hydrogen-optimized structure is used for the SOCME calculations from the ground state reference geometry.” |
