Two-dimensional bond-selective fluorescence spectroscopy: Violations of the resonance condition, vibrational cooling rate dispersion, and super-multiplex imaging

Multidimensional spectroscopies have shaped our understanding of molecular phenomena, but they are often limited in sensitivity. In this work, we describe two-dimensional bond-selective fluorescence-detected infrared-excited (2D-BonFIRE) spectro-microscopy: an ultrasensitive two-dimensional…
