Abstract:To investigate the
relationship between the structural degrees
of freedom around a vibrational probe and the rotational relaxation
process of a solute in solution, we studied the anisotropy decays
of three different N3-derivatized amino acids in primary
alcohol solutions. By performing polarization-controlled IR pump–probe
measurements, we reveal that the anisotropy decays of the vibrational
probe molecules in 1-alcohol solutions possess two decay components,
at subpicosecond and picosecond time scales. On the… Show more
