Ammonia PICI spectrum

Although the ammonia PICI spectrum of TATP is dominated by the m/z 240 [TATP + NH4] ion, attempts to perform CID studies of the ion trap-isolated ion failed to produce a significant yield of product ions. Calculated interaction energies between TATP and the ammonium cation were reported to be less than the peroxide bond dissociation energy [30].The ammonium ion that would presumably be formed by ejection from...
