Pyrolysis products of ammonium perchlorate (NH₄ClO₄) at 483 K were monitored on line and in situ via single photon photoionization reflectron time-of-flight spectrometry (PI-ReTOF-MS) in the photoionization range of 9.00–17.50 eV. The photoionization efficiency curves (PIE) of the subliming product molecules were collected and allowed for detection of three class of products containing chlorine, nitrogen, and oxygen including atoms and free radicals. These results suggest new insight into possible low-temperature decomposition pathways of NH₄ClO₄.
