Jacoby aromaticity factor

Input(s)

$\gamma$: Specific Gravity (unitless)

M: Molecular Weight $(\mathrm{lbm} / \mathrm{lbm} \mathrm{mol})$

Output(s)

$J_{a}$: Jacoby Aromaticity Factor (unitless)

Formula(s)

$$ \mathrm{J}_{\mathrm{a}}=\frac{(\gamma)+\left(\frac{15.8}{\mathrm{M}}\right)-0.8468}{0.2456-\left(\frac{1.77}{\mathrm{M}}\right)} $$
