Infrared microscopy was used to determine di‐ n ‐butyl phthalate, dinitrotoluene, and methyl centralite diffusion profiles in cross sections of nitrocellulose‐based propellant grains. Absorbance of marker functional groups was determined at 25–50 µm intervals from the edge to the center of the sections. Comparison of IR and light microscopical data indicated that the optically visible boundary does not define the entire depth of deterrent penetration into propellant grains.
