Abstract

^13^C and ^1^H nuclear magnetic resonance (NMR) spectra have been obtained in order to identify the six nitration products of pyrene—1‐nitropyrene, 1,3‐dinitropyrene, 1,6‐dinitropyrene, 1,8‐dinitropyrene, 1,3,6‐trinitropyrene and 1,3,6,8‐tetranitropyrene. ^13^C chemical shifts in DMSO‐d~6~ were assigned using empirical rules, with particular emphasis on the additivity of the substituent effects. Carbon spectra of separated dinitromixtures enabled identification of the previously unreported 1,3‐isomer, and proton spectra differentiated the 1,6‐ and 1,8‐ isomers.
