Wave packet interferometry for short-time electronic energy transfer: Multidimensional optical spectroscopy in the time domain

A detailed study of multidimensional time-domain electronic interference spectra for a model complex supporting electronic energy transfer was carried out. The issue of inhomogeneous broadening of the electronic transition frequencies was addressed. It was shown that nonlinear wave packet interferometry, together with the tools of optical phase control and polarization spectroscopy, is directly sensitive at the amplitude level to the dynamics of internuclear motion accompanying and giving rise to energy-transfer surface-crossing transitions.
