Abstract
The i.r. spectra of the β forms of phthalocyanine and its NN′-dideuterio-derivative are recorded. Absorptions resulting from N–H vibrations are assigned to bands at 3273, 1539, and 735 cm–1. Other differences between the spectra of the parent and the dideuterio-derivative in the 760–710 cm–1 region are explained in terms of a lattice vibration, modified by a second-order isotope effect.Keywords
