摘      要：A fragmentation mechanism and characterization for the first time using Direct Analysis in Real Time- Time of Flight-Mass Spectrometry(DART-TOF-MS)of the tetramethylene diperoxide dicarbamide(TMDD)compound were *** MS-spectrum may support other research about devices and detection in real *** mass spectrum of TMDD obtained using DART ionization in the positive-ion detection mode exhibited a strong peak at m/z254representing an ammonium adduct([TMMD·NH_4]~+).There was another peak at m/z237,which represented the protonated molecule([TMDD·H]~+)of *** two peaks corroborated the identity of the *** DART-MS spectra of the TMDD-isotopomer successfully corroborated the respective molecular tails. The principal fragmentation residues also showed coherence according to the number of isotopically labeled atoms on the TMDD *** contrast with other organic peroxides analyzed by this technique,TMDD exhibited substantial *** theoretical modeling results showed that the fragmentation mechanism of the TMDD ion adduct is strongly dependent of the TMDD ring flexibility and the hydrogen bonding formed between the nitrogen and oxygen atoms and the atmospheric proton.
