Optical-based photothermal infrared spectroscopy (O-PTIR) is a relatively new technique that detects changes in infrared absorption by monitoring temperature-dependent fluctuations with a visible probe laser, resulting in a submicron spatial resolution determined by the diffraction-limit of the visible probe. Commercial instruments can achieve a spatial resolution of < 500 nm under ideal conditions, all while operating in far-field, non-contact mode. This workshop will discuss advances in photothermal infrared spectroscopy and how it can be applied to a variety of samples at the ALS infrared beamlines.
