Interference patterns in reflectance and transmittance of a thin platelet of 'Curl inthe Z. exciton region have been analyzed in terms of an extended version of the D'An-drea-Gel Sole theory about microscopic treatment of additional boundary crcndition(ABC). In the extension, quantization effect has been explicitly considered withrespect to exciton motion in a slab. The effect of internal multiple reflection ofpolariton waves and the energy dependence of exciton damping factor havv' beentaken into account. The decay constant of the evanescent exciton wave near surfacehas been treated as an adjustable parameter. The observed spectra by Mita andNagasawa are well reproduced by the simplest extreme case of this theory, i.e., thecase of vanishing contribution from the evanescent wave, which is equivalent to thePekar's ABC.
