(a) Microphotographs of a N₂O sample at 15.8 GPa, before (top) and after (bottom) laser heating. The gold particles are encircled in white (top). The recrystallized matter in the area surrounding the laser-heated gold particles is where the chemical reaction occurred (bottom). (b) Raman spectra of NO⁺NO₃⁻ obtained upon the sample decompression from 55.0 down to 3.9 GPa. The Raman modes marked by asterisks belong to pure molecular nitrogen (Bini et al., 2000
