Near-infrared emission spectroscopy of explosive breakout

The aim of this study was to explore the early time breakout in the near infrared spectrum of various high explosives. Explosives tested include RDX, Composition B, HMX, and PETN, along with RP1 and RP80 detonators in air and nitrogen environments. The first 20 microseconds after detonation were examined using a combination of a rotating filter disk and shutter to gate the exposure after the detonation. The spectral range covered in this study included from approximately 880 to 1660 nm. Various spectrometer systems were used that resulted in two ranges of resolution. Notable spectral features were compared to previous work, and emission spectrum of diatomic and atomic sources were investigated. Simulations of possible molecular and atomic species were studied using the Specair software. The result of this study led to the positive identification of several key emitters, while others remain unidentified.
