Long period SiC polytypes exhibit a number of Raman bands which reflect theirstacking sequence of atomic planes. The Raman spectra of these polytypes can pro-vide irtformation on the phonon frequencies and vibrational amplitudes in the basicpolytype (cubic, zincblende structure). Assuming a zincblende type structure as an ap-proximate structure of SiC polytypes, the relative Raman intensity of folded modes intwo SiC polytypes is calculated with several models of lattice dynamics and comparedwith the observed spectra. In the framework of a siunple bond-polarizability model weshow how the analysis of intensities can be used to rate different phenomenologicalmodels.
