Infrared spectra of photodimers of anthracene, benzo[ a ]anthracene, and tetracene

Abstract

Infrared spectra of the photodimers of anthracene, anthracene-d 10 , tetracene, and benzo[a]anthracene are reported in the region 4000–200 cm −1 . An attempt is made to correlate the observed bands with the proposed structure of the anthracene dimer. The infrared spectra indicate that the dimers of benzo[a]anthracene and tetracene have similar structures.
