β¦ Synopsis
Quadrupole tensor calculatmns are reported for benzene, naphthalene, anthrdcenc, phenanthrene, biphenyl (planar and twisted), p> rene, [ 18]-annulene dnd azulene. Double-zeta and STOJ4G basis sets give similar ratios between naphthalene and benzene components. ST0/4G calculations _give out-of-phne components proportional to the number of valence electrons for nll molecules except azulene.
