    Convenient methods with simple devices comprised of an opticalcell and prisms were proposed for the direct spectrophotometric measurement of adsorbed species at liquid-liquidinterface, using a protonated meso-tetraphenylporphyrinin an aggregate form as an interfacial adsorbate. The spectrum of the aggregate within the visible wavelength region was effectively observed by three kinds of prism-cell assembly for (1) the double-phase transmission method, (2) the multiple attenuated total-internal reflection method and (3) the external reflection method. Characteristics of spectral appearance in each of the methods were described and discussed
