Diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) was used to follow the adsorption kinetics of ethyleneglycol dinitrate (EGDN) on zinc oxide as a function of dosing time. Inhomogeneous broadening of the NO2 antisymmetric stretching vibration was found
to be dose dependent. Through nonlinear curve-fitting techniques, the sum of three component bands was found to reproduce the inhomogeneously broadened envelope and was attributed to two different types of adsorbed EGDN corresponding to on-end and bridged sites on a zinc rich surface of zinc
oxide. The adsorbed EGDN species were characterized by their line-shape parameters and adsorption kinetics.
