Abstract

Variable temperature /303–553 K/ IR spectroscopic studies are made during thermal decomposition of pure and γ-treated ammonium perchlorate /AP/. Decomposition is enhanced by radiation or in the presence of an additive /Gd2O3/. Intensity of the stretching /∼1100 cm−1/ and bending /∼625 cm−1/ frequencies of ClO −4 decrease on heating the KBr matrix even below 360 K. Above this temperature, a broad band develops over 480–510 cm−1 in the pure and γ-treated AP which is attributed to ClO −3 /ν4/.
