Abstract

Time-resolved resonance heterodyne optical Kerr-effect spectroscopy is employed to measure the solvation dynamics of rhodamine 800 in water and D2O. Unlike other large dye molecules, rhodamine 800 solvation dynamics in water exhibits a long-time component which we attribute to hydrogen-bond formation (breaking). We also find a rather unusual large isotope effect which does not exist in other dyes. An important part of the experimental data is a bimodal solvation correlation function with an ultrafast femtosecond component < 100 fs.
