Abstract The theory of preferred orientation determination (crystallographic- or spintexture) by Mössbauer effect is presented for the case of unpolarized and polarized source radiation. The maximum information one can get out from Mössbauer measurements for the case of dipole radiation (M1) are nine expansion coefficients of the texture distribution expanded in a series of spherical harmonics. These coefficients can be obtained by a fitting procedure of the experimentally determined line intensity ratios in an absorption spectrum with rotated source and absorber. The general theory is applied for M1 radiation (Fe57) and the cases of pure Zeeman or quadrupole splitting of source and absorber. Extension to higher multipole radiation can be easily done. Some graphs of possible textures are shown.
