ChemInform Abstract: THE TOPOLOGY AND THE AROMATICITY OF COUMARINS

Chemometrics

“…More esoteric GT studies have employed polyomials (GT4, GT8-9, GT23) and other representations derived from the original graph (GT3) for placing related compounds into useful orders (GT10-12) describe symmetries (GT2, GT2I), stabilities (GT22), or relationships with spectra (GT5) and aromaticity (GT17,GT25). Herndon (GT16) has cautioned against the indiscriminant use of one approach which yields imaginary roots of polynomial equations, in some cases, which is not physically justifyable.…”
