Abstract
Recent studies of the crystallization of cyclotrimethylene-trinitramine (RDX) have shown that the presence of the α- and β-phases of the compound is sensitive to the substrate using drop cast crystallization methods. The specific phase has potential consequences for measurements of the nitrogen K x-ray emission spectrum (XES) that were recently reported for this compound using samples crystallized on In metal substrates. We have determined that the crystallization of RDX on a clean In metal substrate starts out completely as the β-phase but progressively incorporates the α-phase as the film thickens. In addition, we have carried out additional molecular orbital calculations of the N 1s x-ray fluorescence from the valence band, comparing the results expected from the α-and β- phases. The differences due to the presence of the β-phase instead of, or in addition to, the α-phase appear to be minimal.Citation
