The geometries on M(C2H2)+(M=Sc,Ti,V) complexes were completely optimized by using density function theory(DFT)B3LYP/6-311+G(3d,2p) calculations. The normal vibration analysis on M(C2H2)+has been computationally investigated with the same method.

• 采用密度泛函(DFT)计算方法,在UB3LYP/6-311+G(3d,2p)水平上优化了过渡金属正离子乙炔络合物M(C2H2)+(M=Sc,Ti,V)不同自旋态的稳定几何构型,并对此络合物体系的全部振动频率进行了计算和全面分析。
