摘要

Density functional theoretical calculations have been made on the electronic structure of (CH)(n)(BCO)(6-n) (n = 0-6) at B3LYP/6311 + G(d) level. The nuclear-independent chemical shifts (NICS) values calculated using the gauge-including atomic orbitals (GIAO) method were used to assess on the aromaticities of these molecules. The results shows that (CH)(n)(BCO)(6-n) (n = 0-6) species are aromatic.
