N2 - We have used the technique of time resolved resonance heterodyne optical Kerr effect to measure the ultrafast solvation dynamics of rhodamine 800 (R800) and 3,3′-diethylthia-tricarbocyanine bromide (DTTCB) in water and D2O. We find a significant isotope effect in the picosecond range for R800 but we do not reveal it for DTTCB. We explain the R800 results by a specific solvation due to formation (breaking) of an intermolecular solute-solvent hydrogen bond. Another important part of the experimental data is a bimodal solvation correlation function with an ultrafast femtosecond component < 100 fs.
