It is shown that multiple quantum filtration may be used to rapidly assign the 1H NMR spectra of polycyclic aromatic hydrocarbons. This technique is faster than two-dimensional chemical shift correlation spectroscopy and gives very similar information. In addition, since multiple quantum filtration simplifies spectra by elimination of some resonances, it can be invaluable for assignment of resonances that are unresolved due to inadequate field strength. Application of this technique to assignment of the 1H NMR spectra of benzo[a]pyrene-7,10-dione, 10-methylbenzo[a]pyrene, and 6-acetoxybenzo[a]pyrene is presented.
