    We present the equivalent width measurements of the hydrogen H α line, the oxygen near-IR triplet OI 7772–5 $/AA$ and of a number of FeII lines in several B, Be, and shell stars in optical and near-infrared regions. A study of the correlations between all these measured quantities has been made. The correlations of strength of lines with collected data of the near-IR color excess, the rotational velocity and the intrinsic polarization are also obtained and presented.
