Web3 sep. 1999 · Singlet states are antiaromatic, their dearomatisation is mostly due to the bond length alternation. Correlation analysis applied to basic indices of aromaticity (δ(1 H). NICS, HOMA and χ) practically shows the lack of any correlation in sub-groups consisting of triplets or singlets. Triplet states of 4nπ-annulenes are more aromatic than ...
