Fig. 7From: Zombie cheminformatics: extraction and conversion of Wiswesser Line Notation (WLN) from chemical documentsLocant Paths shown on chemical structures for a Phenanthrene and b Phenalene. WLN alphabetic indexing is shown on each atom. For Phenalene, the highest priority atom is the perifused center, and therefore it takes the starting point. Any further peri-fused points will force the path to travel in that directionBack to article page
