A new paper many years in the making! We lay out a detailed practical discussion of how we implement broadband supercontinuum IR sources as a probe in ultrafast IR experiments, including many of the things we have learned working with it over the years. We hope this...

Our new paper on the IR spectroscopy of hydrated zeolites is out in JPCB! We revisit an enigmatic doublet in the IR spectrum of HZSM5 at low hydration state and argue that the accepted assignment as a Fermi resonance is difficult to reconcile with the spectral...
