Connection tables interconversion

Development of computer methods for the interconversion of chemical nomenclatures to and from molecular formulae, connection tables, and structural diagrams followed and seems to continue to follow two separate paths. On the one hand there are a great many reports, mainly from university sources, dealing with translation of systematic names into structural diagrams, and on the other hand there is relatively limited literature on translation of structural diagrams directly into systematic chemical names. Although these are two opposite directions of the same conversion, they have in practice very little in common as far as algorithms and applicable methods are concerned. 

A detailed study was carried out on the radical anion derived from (10c) (Table 2) in connection with the conformational analysis of heteroaromatic carbonyl compounds. Notably different ESR signals could be observed originating from distinct rotational isomers. Unfortunately no information on the interconversion of the rotamers of (10c) could be definitely derived since these radicals were highly unstable at the temperature necessary for interconversion <74JCS(P2)562>.
