| 英文摘要 | Vibrational and structural dynamics of two transition metal carbonyl complexes, Mn(CO)(5)Br and Re(CO)(5)Br were examined in DMSO, using ultrafast infrared pump-probe spectroscopy, steady-state linear infrared spectroscopy and quantum chemistry computations. Two carbonyl stretching vibrational modes (a low-frequency Al mode and two high-frequency degenerate E modes) were used as vibrational probes. Central metal effect on the CO bond order and force constant was responsible for a larger E-A(1) frequency separation and a generally more red-shifted E and Al peaks in the Re complex than in the Mn complex. A generally broader spectral width for the Al mode than the E mode is believed to be partially due to vibrational lifetime effect. Vibrational mode-dependent diagonal anharmonicity was observed in transient infrared spectra, with a generally smaller anharmonicity found for the E mode in both the Mn and Re complexes. |
