Abstract
Modern techniques for performing ultrafast transient mid-infrared spectroscopy using turnable, broadband infrared probe pulses with multi-channel CCD and infrared focal plane array detection is presented. Novel application of these picosecond and femtosecond methods performed at NIST, for studying hydrogen-bond and vibrational energy dynamics of molecular systems in solution, electron transfer at semiconductor interfaces, vibrational coherent control and metal-carbonyl self-associated reactions are reviewed. Prospects of extending these techniques to the far-infrared spectral region for extracting biopolymer dynamics is briefly discussed.
