Abstract : The propellant under study in this investigation is HMX2. Low pressure characteristics of HMX2 are quite different from either HMX1 or M-30. Propellants similar to HMX2 will find application for rockets where slow burning rates and low flame temperatures are desirable and for tank guns where low vulnerability is extremely important. Optical absorption and emission spectroscopy has been applied to HMX2 (a nitramine propellant exhibiting a 'dark zone') burning over a pressure range of 1.2 to 1.8 MPa nitrogen. Emission signals from CN have been observed and profiled, as well as absorption signals from NO. Large broadband absorptions occurred in the wavelength range appropriate for NO absorption. There was significant NO present in the dark zone as evidenced by 100% absorption occurring in the (0,0) vibrational band of the A 2Sigma - x 2Pi transition.
