Optical properties of RDX (cyclotrimethylene-trinitramine) and HMX (cyclotetramethylenetetranitramine) were obtained from 2.5 to 18 gtm using scattering-corrected KBr pellet-FTIR transmission spectrometry. Absorption index (k) was measured directly and refractive index (n) was deduced using dispersion theory. At 10.6 μm the absorption coefficients were RDX, 2800 cm−1 and HMX, 5670 cm−1.
