英文摘要the time-dependent density functional theory (tddft) method has been carried out to investigate the excited-state hydrogen-bonding dynamics of 4-aminophthalimide (4ap) in hydrogen-donating water solvent the infrared spectra of the hydrogen-bonded solute-solvent complexes in electronically excited state have been calculated using the tddft method we have demonstrated that the intermolecular hydrogen bond c= o h-o and n-h o-h in the hydrogen-bonded 4ap-(h2o)(2) trimer are significantly strengthened in the electronically excited state by theoretically monitoring the changes of the bond lengths of hydrogen bonds and hydrogen-bonding groups in different electronic states the hydrogen bonds strengthening in the electronically excited state are confirmed because the calculated stretching vibrational modes of the hydrogen bonding c=o, amino n-h, and h-o groups are markedly red-shifted upon photoexcitation the calculated results are consistent with the mechanism of the hydrogen bond strengthening in the electronically excited state, while contrast with mechanism of hydrogen bond cleavage furthermore, we believe that the transient hydrogen bond strengthening behavior in electroniclly excited state of chromophores in hydrogen-donating solvents exists in many other systems in solution (c) 2010 wiley periodicals. inc. j comput chem 31 2157-2163. 2010
