Scientific paper

A high-dispersion spectroscopic study is conducted of three marginally peculiar CP stars, for which model atmospheres were chosen on the basis of hydrogen line profiles while atmospheric elemental abundances were ascertained by the synthetic-spectrum method. While the results thus obtained do not facilitate an unambiguous classification of the stars as distinct CP1-CP4 types, 36 Aur's overabundance of Cr and Fe, as well as its photometric variability and the presence of a surface magnetic field, are signs of the CP2 group. HR 7028 could be assigned the CP3 type, but only on the basis of the Hg 3984 line's presence in its spectrum. 21 Aql also displays some characteristics of the CP2 group.
