High Pressure Raman Spectroscopy of 4-Azidobenzoic Acid

Abstract

With the rapid development of science and technology, people’s demand for energy materials is increasing, and researchers’
exploration of energy materials is also more and more in-depth. Azide is a kind of nitrogen rich energetic material. In recent years, the
research on azide mainly focuses on the synthesis of polynitrogen under the condition of changing pressure. This is because under the action
of pressure, the azide group in the azide will hybridize the electronic orbit, and the adjacent azide groups will re combine in the form of
single bond, so azide is considered to be an ideal precursor for the synthesis of polynitrogen under high pressure. In this paper, the Raman
spectra of 4-azidobenzoic acid at ambient pressure were analyzed, the high-pressure Raman spectra of 4-azidobenzoic acid were measured,
and the phase transition of 4-azidobenzoic acid under high pressure was discovered.
