A facile pressure-induced disproportionation of nitric oxide occurs at 176 K and 1.5 GPa. The reaction products are N/sub 2/O/sub 4/, N/sub 2/O, and a small, variable amount of N/sub 2/O/sub 3/ as identified by infrared, Raman, and visible absorption spectroscopies. No free NO, N/sub 2/O/sub 2/ or NO/sub 2/ is observed after warming the sample to room temperature. The N/sub 2/O/sub 4/ product subsequently photolyzes to form N/sub 2/O/sub 3/ and NO/sub 2//sup +/NO/sub 3//sup -/, and evidence for the nitrite form of N/sub 2/O/sub 4/ is reported. The N/sub 2/PO product is stable, once formed, to 14.0 GPa. 27 references, 7 figures.
