Abstract
The preliminary determination of the atmospheric chemical composition of th e Li "spotted" roAp star HD 83368 has been obtained by the synthetic spectr um method. The locations of two lithium spots are determined by the procedu re of "mapping", based on the Doppler line shifts for different rotation ph ases.
