Evolution of Ultrafast Vibrational Dynamics During Sol–Gel Aging

A longitudinal 1D- and 2D-IR spectroscopy study is presented in which the homogeneous and inhomogeneous contributions to the line shape of a surface-bound SiH vibration are monitored in a silica sol–gel while it ages. The vibrational data are complemented by time-lapse 29Si NMR and rheological meas...
