Abstract

Photophysical and -chemical spectral holeburning is a well established technique in various spectroscopic fields and for different time-scales. Its ultrafast counterpart in the infrared however was lacking although detailed dynamical information can be provided by this powerful spectroscopy. We have, for the first time, observed spectral holes in the infrared on the picosecond time scale studying the OH stretching vibration as a spectroscopic probe of hydrogen bonds in condensed matter. In this report results on the terpolymer polyvinylbutyral (PVB) will be discussed.
