Ultrafast solvation dynamics in water: Isotope effects and comparison with experimental results

“…35,36 In D 2 O these band positions are at 505 and 64 cm Ϫ1 , respectively. 36,41 In this study we have found that excellent agreement with experiment can be achieved if the 193 cm Ϫ1 band is treated as overdamped ͑see the discussions below͒. Note that in the previous treatment 13͑a͒ this mode was treated as underdamped.…”

“…The reason of this surprising behavior is not well understood. 41 One possibility is that this mode is somehow damped at high temperatures. The local anharmonicity is more important in the INM analysis, but possibly not that important in the macroscopic experiments, like dielectric relaxation or Raman spectroscopic studies.…”
