Easy Access to Experimental Bond Dissociation Energies in Solution Using 2D‐IR Spectroscopy

open access: yesAngewandte Chemie, EarlyView.
How strong is a chemical bond? The answer is hidden in the spacing of vibrational levels. This anharmonic fingerprint yields the energy needed to break an X─H bond from a single measurement, turning an ultrafast observable into a thermochemical quantity directly in the solvent of interest.
