Linear dichroism of free base tetraphenyl porphin
Artikel i vetenskaplig tidskrift, 1976

Linear dichroism (LD) spectra of tetraphenyl porphin in oriented polyethylene, polypropylene and polyvinylchloride matrices were studied. A negative LD component at 400 nm is suggested to be due to an out-of-plane polarised transition. From evidence of changed polarisations within the (0,0) visible bands it is suggested further that the matrix may play an active role in perturbing the electronic spectrum by stimulating vibronic transitions with differing polarisations.
