Abstract
We apply a Fourier filtering technique for the global removal of coherent contributions, like perturbed free-induction decay, and noise, to experimental pump–probe spectra. A further filtering scheme gains access to spectra otherwise only recordable by scanning the probe’s center frequency with adjustable spectral resolution. These methods cleanse pump–probe data and allow improved visualization and simpler analysis of the contained dynamics. We demonstrate these filters using visible pump/mid-infrared probe spectroscopy of ligand dissociation in carboxyhemoglobin.
