1Excited and ground state vibrational dynamics revealed by two-dimensional electronic spectroscopy.

Caram JR1, Fidler AF, Engel GS.

J Chem Phys. 2012 Jul 14;137(2):024507. doi: 10.1063/1.4733710.

Broadband two-dimensional electronic spectroscopy (2DES) can assist in understanding complex electronic and vibrational signatures. In this paper, we use 2DES to examine the electronic structure and dynamics of a long chain cyanine dye (1,1-diethyl-4,4-dicarbocyanine iodide, or DDCI-4), a system with a vibrational progression. Using broadband pulses that span the resonant electronic transition, we measure two-dimensional spectra that show a characteristic six peak pattern from coherently excited ground and excited state vibrational modes.
