On the basis of the half-widths of the spectral lines He I λ4471 Å and Mg II λ4481 Å the rotation parameters (inclination i of the rotation axis and rotation velocity ω) were determined for 69 stars of spectral classes B0 - B3. New values for v sin i were determined and compared with data of the catalogue.
