The use of remote-sensing diffuse-reflectance optics to obtain Fourier-transform mid-infrared spectra from sand-blasted gold, aluminum, and steel surfaces as a function of position in order to monitor the spatial distribution of oil over the surface is described, and used to map the spread of an 0.85 mu g safflower oil droplet with time, to calibrate the spectra for film thickness near 1 mu m, and to monitor the oil oxidation that limited the extent of the stain.
