Abstract:

The solvent reorientation process of the intramolecular charge-transfer (ICT) process of the (p-cyanophenyl)pentamethyldisilane-(H2O)2 (CPDS-(H2O)2) cluster in the excited-state was investigated by transient infrared (IR) absorption spectroscopy. It was found that there are at least two isomers in the charge-transfer (CT) state: one of the isomers exhibits a band of a pi-hydrogen-bonded OH stretch of the water moiety. Analyses of the IR spectra in the dominant isomers revealed that water molecules are hydrogen-bonded with each other in the CT state. This indicates that the reorientation process of the water molecules takes place to form such a dimer structure during the ICT process.
