Infrared Spectro-microscopy Operation Calendar
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 content of samples. The technique is easy-to-use, non-destructive, does not require markers and is useful in astronomy, chemistry, earth, forensic (pdf), and cultural heritage investigations for example. Scanning the sample allows to record chemical maps. IR spectroscopy allows to study low energy excitations in soft and condensed matter systems as well.- The use of a synchrotron source is advantageous for the study of small or very small samples.
- A small source size is indispensable to produce well collimated light for very high resolution work.
- The broad synchrotron source is a pulsed and well suited for pump&probe experiments.
