I apparently have watched too much explosions & fire / extractions & ire, because my immediate thought on seeing the parent comment was that "yeah, it's gonna decompose before it vaporizes, and if it's hypergolic with itself that'll be fun"
Apparently, watching an Aussie with a backyard shed full of mysterious chemicals and reagents has me assuming that any mysterious, unmarked liquid that needs to be identified is probably explosive.
AFAIU most methods of spectroscopy work by measuring the atomic composition of the materials anyways not the exact structure and bonds so a chemical change shouldn't matter much.
