| Infrared (IR) spectroscopy is based on the absorption of infrared radiation. Absorption at low energy < 1 eV is, most of the time, a signature of molecular vibrations. Thus IR methods are used to investigate the chemical composition of samples. The technique is easy-to-use, non-destructive, and is useful in astronomy, chemistry, biology, forensic, life-sciences, for example. IR spectroscopy allows to study low energy electro-dynamics in soft and condensed matter systems. The use of a synchrotron source is advantageous for the study of small or very small samples. The small and brilliant source point is of advantage for very high resolution work as well. last up-date 10.03.2010 |
