Transient 2D IR spectroscopy from micro- to milliseconds


Hamm, Peter (2021). Transient 2D IR spectroscopy from micro- to milliseconds. Journal of Chemical Physics, 154(10):104201.

Abstract

A new application of high-repetition rate, femtosecond Yb-laser/amplifier systems is introduced: transient 2D IR spectroscopy covering the time range from micro- to milliseconds. This approach intertwines the measurement of 2D IR spectra with the time separation from an actinic pump pulse and utilizes the high repetition rate of these lasers systems in two ways: by offering a high time resolution (10 µs) and by enabling the measurement of many 2D IR spectra. The well-studied photocycle of bacteriorhodopsin is used as a demonstration object in this proof-of-principle experiment.
