Bruker Vertex 80V (under vacuum – to minimize noise and water vapor contamination; cryostat option; detectors: Bolometer, DTGS, MCT; spectral range between 100 and 6000 cm-1). It is interfaced with a pulsed Continuum Surelite laser with OPO (tunable between 440 and 670 nm) to study photoinduced processes. This instrument is dedicated to time-resolved FTIR measurements (rapid-scan, step-scan) with a time resolution of 100 ns.
