CH(CH3)3 的耦合CH伸缩和弯曲振动的纠缠

以不同的多极量子数和初态，我们用约化的线性熵研究CH(CH3)3 的耦合CH伸缩和弯曲振动的动力学纠缠，结果表明：在多极量子数大于等于３时，态|0,2N>的最大纠缠能在较短的时间内得到；态|N,0>的纠缠振荡频率比态|0,2N>的要小，而振荡的幅度要大．

It isshown that for a given polyad $N geq 3$, a maximum entanglementfor state $|0,2Nrangle$ can be obtained with a shorter time, andthe entanglement oscillatory frequency for state $|N,0rangle$ isshorter than that for state $|0,2Nrangle$, where the amplitude ofthe former state is larger than that of the later one.
