  为了阐明光化学电荷转移和异源准分子形成过程的基本过程的细节，也为了将获得的结果与瞬态吸收光谱测量的结果进行比较，我们通过 ps 时间分辨方法检查了以下分子内异源准分子系统使用锁模 Nd3+ 进行荧光测量：YAG 激光器和条纹相机：p-(CH3)2–NC6H4–(CH2)n–(9-蒽基) (n=0, 1, 2, 3), p-( CH3)2NC6H4–(CH2)n-(1-芘基) (n=1, 2, 3) 和 9,9'-联蒽基。已经清楚地证明了亚甲基链长、溶剂极性和粘度对分子内电荷转移过程的影响。得出的结论是，在 n=3 化合物中均未识别出在基态具有夹心构型的分子，由于采用夹心构型所需的广泛构象变化，在己烷中形成异源准分子需要几纳秒。构象变化和溶剂重新定向都涉及...

It is concluded that molecules with sandwich configuration in the ground state are not recognized in both n=3 compounds, and it takes a few ns for the heteroexcimer formation in hexane because of an extensive conformation change necessary to

  The picosecond state-selective dynamics and photochemistry of the molecule A–(CH2)3–φ, where A and φ are aromatic chromophores, was studied under collision-free conditions in a supersonic beam. Time-resolved fluorescence measurements of the reactant and the charge transfer (exciplex) product were undertaken as a function of specific vibrational energy above the zero point level of S1. From these studies along with an analysis of the excitation spectra, dispersed flourescence, and quantum yields, the following results and conclusions were reached: (i) IVR is much faster than reaction at all excess energies studied. (ii) The energy threshold for product formation is E0≂900 cm−1 (2.6 kcal/mol). The analysis of the rates using an effective temperature model gives a frequency factor of A0≊1.2×1010 s−1. Four torsions were identified as critical to the reaction dynamics which were modeled according to a multidimensional reaction coordinate using an RRKM scheme. (iii) The thermodynamics of the isolated charge transfer product indicates strong stabilization ΔH=−9.2 kcal/mol and extensive charge transfer, the static dipole moment is 13 D, and the charge transfer contribution to the total electronic wave function ‖c2‖2 is 0.86. (iv) A comparison of the present work to solution phase studies of A–(CH2)3–φ indicates similar static properties but different dynamics. The calculated thermal (room temperature) reaction time for exciplex formation in the vapor (540 ps) was compared to the shortest observed value in solution (1.4 ns) to assess the role of the solvent on the chain motions which lead to product formation.
