Abstract: The computer simulation method of the solid powder pattern in the presence of anisotropic chemical shift effect and nuclear electric quadrupole interaction is presented. The computer program was designed for the powder pattern of the central transition of nuclei with half-integral spin. The "noise" and error in the simulation spectra as well as the spectra simulation procedure were analysed.
