Hydrogen Bonds in a Polymer Investigated by Picosecond Infrared Hole Burning,
Abstract
In the past spectral hole burning was intensively investigated for dye molecules in solid matrices. The long-lived photochemical holes at low temperature gave valuable and detailed information on the structural properties of the molecular surrounding. e.g. polymer matrices. More recently, persistent Photochemical hole burning at low temperatures was extended to the infrared for smaller molecules in rare gas or glass matrices and to hydrogen bonded polymers. Recently we observed transient spectral holes in the infrared absorption spectrum of a polymer at ambient temperature. The analysis of the hole Parameters gives valuable information on the hydrogen bonds in the disorder system. Our experimental technique is a double resonance spectroscopy with intense tunable picosecond pulses. Details of the measuring system have been described recently.
