With transient IR hole-burning spectroscopy we observe large variations in the homogeneous linewidth of the vs(O-D) stretch vibration of differently hydrogen-bonded surface hydroxyls in zeolite catalysts. The linewidth is very sensitive to the frequency of the vs(OD.X) hydrogen-bond vibration. By varying this frequency we obtain conclusive information on the coupling between the vs(O-D) and the vs(OD.X) modes.
