dc.description.abstract	Reflection and wavelength modulated reflection spectra were investigated at temperature 10 K in CdAl2S4 crystals. Ground and excited states of three excitonic series (A, B and C) were found out. Contours of reflection excitonic spectra were calculated and main parameters of excitons and bands in k = 0 were determined. The effective mass of electrons mc is equal 0.30m0 and holes masses mv1, mv2 and mv3 are equal to 1.55m0, 0.90m0 and 2.07m0, respectively in Γ point of Brillouin zone. Valence bands V1 - V2 splitting due to crystal field (141 meV) and bands V2 - V3 splitting by spin-orbital interaction (152 meV) were estimated.	en_US
