Abstract

Mid-infrared cavity ring-down spectroscopy (CRDS) has been employed in this study to examine the hydride stretching region of methyl azide and its pyrolysis product methyleneimine. The absorption spectrum of methyl azide over 2835–3085 cm−1 was recorded, and the integrated absorption cross section was determined. The pyrolysis of methyl azide and subsequent production of methyleneimine was observed at various wavenumbers. Using IR CRDS, we were able to observe vibrational transitions of methyleneimine without interference from the methyl azide precursor. Our previous UV CRDS study showed that electronic transitions of methyleneimine overlapped with those of methyl azide. IR CRDS should thus be useful for the detection of polyatomic transient intermediates without interference from precursors.
