Raman spectroscopy is used to investigate the degree of order found in in situ photopolymerised films exhibiting polarised emission. Studies indicate that the mixed system shows differing degrees of order for its two molecular components. The degree of order was measured in the liquid mesophase for the mixed monomers prior to polymerisation and was found to be in close agreement with the order of the two components measured in equivalent cured films.
