## Abstract Raman spectra of a 3βmethylβ4βnitropyridine __N__βoxide crystal were investigated as a function of pressure in a diamondβanvil cell up to 93 kbar at room temperature. The crystal shows successive reversible phase transitions at 8, 20 and 60 kbar. Above 60 kbar, all of the external Raman
