Abstract

Two approaches that use femtosecond infrared pulses to examine protein dynamics by means of nonlinear IR spectroscopy are described. In the first we dissect the featureless peptide amide-I band and introduce two-dimensional IR spectra [1]. In the second, the correlation function of the frequency fluctuations of a vibrational mode in the active site of carbonic anhydrase and heme pocket of hemoglobin is determined by three-pulse IR photon echoes [2]. These experiments permit the study of ultrafast dynamics without the requirement of chromophores.
