F number is a number used in the chemistry of polycyclic aromatic hydrocarbons (PAHs) as a descriptor of their molecular size. It was proposed by R.J. Hurtubise ''et al'' in 1977.〔J.F.Schabron, R.J.Hurtubise and H.F.Silver, Anal. Chem., 49, 2253 (1977)〕 ==Calculation== From a PAH it can be calculated using the formula: F = B2 + C12 - R / 2, where B2 is the number of double bonds C12 is the number of primary and secondary carbons R is the number of non-aromatic rings. 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「F number (chemistry)」の詳細全文を読む スポンサード リンク
