摘要：
The origin of ultraslow component of solvation observed in an aqueous protein solution is studied by femtosecond up-conversion. It has been observed that solvation dynamics in hen egg lysozyme and lysozyme-cetyltrimethylammonium bromide (CTAB) aggregate exhibits a nearly twofold slowing down when the solvent H2O is replaced by D2O. The deuterium isotope effect suggests that water is the main polar species responsible for the observed ultrafast solvation dynamics in the aqueous protein solution.
