Popis:	Raman microscopy was used to determine the methylcentralite (MC) concentration profiles diffused into single-base (nitrocellulose) (NC) and double-based (nitrocellulose/nitroglycerine) (NC/NG) small-arms propellant grains. External and internal concentration profiles were determined by measuring the concentration of MC relative to the NC and NC/NG at 5-μm intervals into the grain from the edge inward and the perforation edge outward. The external profile was constant with a diffusion and interaction mechanism, i.e., a level concentration of deterrent through the outer region of the grain followed by a gradual dropoff in concentration with distance into the grains, whereas the internal profile was found to be dependent on perforation size with either a diffusion and interaction mechanism profile or a gradual decrease in concentration profile.
