Abstract
Objective To establish one infrared spectroscopic analytic method about gun-purposed propellant.Methods Gun-purposed propellants were qualitatively analyzed with infrared spectroscopy, and consecutively having their spectral detection and comparison carried out into the single/double constituent propellants of both different production time and type.Results Nitrocellulose was detected as the principal component of gun-purposed propellant (either single- or double-constituent), demonstrating its main infrared specific absorption peaks at 1635, 1272, 1121, 1065, 999, 820cm-1. The distinction between single and double constituent propellants can be identified through the strength and shape of infrared absorption peaks at 1719, 1595, 1496, 1372 cm-1. The single-constituent propellant is no significant difference of infrared spectrum when dissimilar guns fire it, and neither is either the double-constituent propellant or 7.62mm rifle-exclusive propellant of different production time.Conclusions Infrared spectroscopy can be used for rapid and accurate identification of single- and/or double-constituent gun-purposed propellants, yet unable to distinguish either the firing guns or the production time of propellant.
