Abstract
A novel slab optical waveguide (SOWG) technique with a white light exc itation source was applied to the spectroscopy of LB monolayer samples . Absorption spectra of a Cu-porphyrin complex in LB films at concentr ations of 0.1-0.5 monolayers were observed in the wavelength range of 380 to 650 nm. Polarized spectra giving information on the molecular o rientation in the ordered thin films were also measured.
