National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Spectral Characterization of RDX, ETN, PETN, TATP, HMTD, HMX, and C-4 in the Mid-Infrared Region.

Publication Date	2014

Page Count	50
Abstract	We report on the complex optical constants (n and k) of RDX, ETN, PETN, TATP, HMTD, HMX, and C-4 as determined by variable angle spectroscopic ellipsometry (VASE) over the mid-infrared (MIR) wavelength range from 2.5 to 16.7 micro m (4000 to 600 cm expn -1). The samples were prepared for analysis by airbrushing onto a zinc selenide (ZnSe) crystal and then analyzed in attenuated total reflection (ATR) mode. The optical constants of HMX and RDX are compared with previously reported values. No previously reported studies of the optical constants of ETN, PETN, TATP, and C-4 were found in the literature.
