2D-IR Photon Echo Spectroscopy of Liquid H2O — Combination of Novel Nanofluidics and Diffractive Optics Deciphers Ultrafast Structural Dynamics
2D-IR photon echo studies of the OH stretching vibration in pure liquid water are presented. At room temperature, a 50-fs decay of structural correlations is found. The temperature dependence of the vibrational dynamics is investigated.
