Summary
We measured twelve alkali cyanide samples that were also sent to ORNL and PNNL collaborators. While results indicate distinct δ¹³C and δ¹⁵N values that would be useful to signature studies, the alkali cyanides, especially NaCN, show chemical breakdown during storage that will influence forensic analysis. Carbon and nitrogen stable isotopic compositions of raw materials used to synthesis TETS were measured. Results indicate wide ranges in δ¹³C and δ¹⁵N values. Using these raw materials, LLNL scientists synthesized three batches of TETS following published procedures. Stable isotopic measurements of TETS synthesis products indicates nitrogen ({var_epsilon} ¹⁵N = -1.7 to -0.8) and carbon ({var_epsilon} ¹³C = -1.0 to -0.1) fractionation during production.
