Abstract
In this paper observations of Fe II emission lines of multiplet 49 are presented for nine southern Be stars. The radial velocity measurement s performed on the line profiles confirm the results previously obtain ed by other authors which were derived using single Fe II lines of dif ferent multiplets. They are of kinematic nature and concern the correl ations of line widths with the V sin i and the extent of the Fe II lin e formation region compared to that of Balmer emission lines. The stud y of multiplet 49 leads us to conclude that its components are optical ly thick.
