I would like to present the study of a selected group of pre-cataclysmic detached binaries: RE J0720--318, EC 11575--1845, MT Ser. The analysis is based on phase-resolved spectra in the 6000--9000Å region, and photometry in the V, R and I-bands. The spectral and photometrical observations were made simultaneously. In order to model our multicolor light curve of RT And we used the packages of Wilson (1979, 1983) for a light curve synthesis.
