Abstract
A relationship between the shape, particularly the calculated length-to-breadth ratios, of polycyclic aromatic hydrocarbons (PAH) and their reversed-phase C18 liquid chromatographic (LC) retention is described. In general, when isomeric PAH are compared, tha LC retention increases with increasing length-to-breadth ratio. Retention data and length-to-breadth ratios for 100 PAH are compared. Tha elution orders for methyl-substituted fluorenes, anthracenes, phenenthrenes, pyrenes, fluoranthenes, benzo[c]phenanthrenes, benz-[a]anthracenes, chrysenes, and benzo[a]pyrenee are reliably predicted from the calculated length-to-breadth ratios.Keywords
