| Abstract: | Based on characteristics and connectivity of the groups in molecules, the group contribution method and topological method was combined together, a new method was developed which can be used to calculate the density of alkyne from molecular structure. The calculated results showed that the calculated density of alkyne were in good agreement with the experimental data, and the mean relative deviation was 0.56% for 85 alkynes, and had advantages over the group contribution method. |
