Title: | Low-lying excited states of light-harvesting system II in purple bacteria | Authors: | Ng, Man-Fai Zhao, Yang Chen, Guan Hua |
Keywords: | DRNTU::Science::Chemistry::Biochemistry | Issue Date: | 2004 | Source: | Zhao, Y., Ng, M. F., & Chen, G. H. (2004). Low-lying excited states of light-harvesting system II in purple bacteria. Physical review E, 69, 1-4. | Series/Report no.: | Physical review E | Abstract: | The low-lying excited states of a B850 ring of Rhodospirillum (Rs.) molischianum are determined accurately by a semiempirical INDO/S method. Results obtained are found to fit extremely well with a Frenkel exciton model with long-range dipolar interactions, and the spatial size of the electron-hole pair is confirmed to fall predominantly within one bacteriochlorophyll with a small leakage to its nearest neighbors. More importantly, the nearest neighbor exciton coupling constants are found to be close to those evaluated directly from dimers, and thus, an existing discrepancy between calculated results of dimers and B850 rings has been resolved. | URI: | https://hdl.handle.net/10356/91858 http://hdl.handle.net/10220/6727 |
