Abstract : The use of tunable infrared lead salt diode lasers as spectrally bright light sources for infrared reflection absorption spectroscopy (IRRAS) at interfaces will be presented. This new spectroscopy permits in situ, non-intrusive optical probing of the vibrational fingerprint spectrum (500-2000/cm) with sub-monolayer sensitivity at metal interfaces and can work through any moderately transmissive ambient. Recent results and instrumental developments will be presented.
