Uncovering Coherent and Incoherent Vibrational Interactions in a Transition Metal Mixed Valence Complex Using Femtosecond Two-Dimensional Infrared Spectroscopy

Femtosecond polarization-selective nonlinear infrared spectroscopies reveal a detailed molecular picture of coherent and incoherent vibrational relaxation dynamics of a cyano-bridged mixed valence complex in a polar solvent.
