有机化合物分子体积的加和性 Ⅱ.常见官能团的拓扑体积

有机化合物中各种常见官能团（羟基-OH,硫酸基-SH,醛根-COH,羰基-CO-,羧酸根-COOH,酯-COO-,酰基-COCl,-COBr,腈-CN,硝基-NO₂;,胺基-NH₂,=NH、≡N,卤取代基-F、-Cl、Br、-I以及苯、酚环等）的拓扑体积都近于常数。这些官能团之间及其本身在拓扑体积方面具有和谐而统一的可加和性。得到了一套普适的官能团拓扑体积数值表。

Additivity of Molecular Volume for the Organic Compound II. The Topological Volume of Ordinary Functional Groups in the Organic Compound

Everyone of the ordinary functional groups in the organic compound approximates to a constant respectively. The topological volume of common functional groups themselves or between themselves are of harmonious and unified additivity. The authors have given a series of universal topological volume values of the common functional groups in the organic compound (see table)
