The kinetics of a key noncovalent, hydrogen bonding interaction was studied in situ using coherent anti-stokes Raman scattering (CARS) microspectroscopy in a microfluidic device. The association of model compounds, pyridine and hexafluoroisopropanol, was quantitatively monitored with submicrometer resolution. Lower limits for the very high formation and dissociation rate constants of the model 1:1 pyridine–hexafluoroisopropanol hydrogen bonded complex in dichloromethane-d₂ were determined to be k₁ > 10⁵ M–¹s–¹ and k–₁ > 333.3 s–¹, respectively.
