Density Functional Theory in connection with accurate LCAO basis sets and norm-conserving pseudopotentials were used to study two issues which are (1) The Selective Functionalization of Single-Walled Carbon Nanotubes with Diazonium Radical and (2) The Molecular Dynamic Simulated IR Spectrum of Adsorbed C3H3 and I on the Ag(111) Surface.For the first, we investigated (1) NO2C6H4 direct addition (2) NO2C6H4N2 dissociative addition reaction on semiconductor (8,0), metallic (9,0)and(5,5) carbon nanotubes.

第一部分模拟的结果显示，在半导体性质(8，0)和金属性质(9，0)、(5，5)奈米碳管上，硝基苯自由基(NO2C6H4)的直接加成反应於不同导电性质的奈米碳管间不具有选择性，而硝基苯重氮化合物自由基(NO2C6H4N2)的解离吸附反应会选择性的与金属性质奈米碳管发生反应，因为在金属性质的系统中，奈米碳管於过渡态时会藉由电荷的转移来稳定过渡态的结构，进而帮助反应更快的进行。
