Abstract
In an optical bomb Octogen has been burnt under various pressures and the intensity distribution was measured with a spectrometer system. The detected CN- and NH-Spectra were then compared with calculated spectra. Under the assumption of a thermal equilibrium a temperature can be related to an intensity distribution. With a least-squares-fit routine calculated spectra were then fitted to the experimental spectra. The resulting temperatures are 2600 K by analysis with CN-Spectra and 2500 K with NH- Spectra. For comparison the adiabatic flame temperature of Octogen is 2900 K.
