✦ Synopsis

Linear dicluoism (LI>) spectra 0: tetraphcnyl porphin in oriented polyethylene, polypropylene and polyvinylchloridc matrixes were studied. A negative LD component at 400 nm is su ggested to be due to an out-of-plant pohrised transition.

From evidence of changed polarisations within the (0,O) visible bands it is swgcstcd further that the matrix may play an active role in perturbing the electronic spectrum by stimulating vibronic transitions with differing pohrisations.
