Phasing problem of heterodyne-detected two-dimensional infrared spectroscopy


Backus, E H G; Garrett-Roe, S; Hamm, P (2008). Phasing problem of heterodyne-detected two-dimensional infrared spectroscopy. Optics Letters, 33(22):2665-2667.

Abstract

rigorous method is presented to measure and adjust the phase difference between the two pulse pairs used in heterodyne-detected 2D-IR spectroscopy with an accuracy better than |Delta phi|=0.1 rad. The method, which can easily be automated, avoids the otherwise tedious measurement of the much weaker pump-probe spectrum as a reference, which is the commonly used approach to phase 2D-IR spectra in a postprocessing step.
