Research notesThe infrared spectra of peroxybenzoic acids—II: Disubstituted peroxybenzoic acids

Bands characteristic of the peroxycarboxyl group are described for a number of disubstituted peroxybenzoic acids. The evidence suggests probable non-equivalency of intermolecular hydrogen bonds in the investigated 2,5-disubstituted peroxybenzoic acids in the solid state.
