本文用弹性力模型计算了C_2H_2晶体的振动光谱,获得了与光谱实验吻合很好的结果,对于C_2D_2C_2HD以及CC ̄(13)H_2同位素颖积也作了讨论。
In this paper, the vibrational spectra of C_2H_2 crystals have been calculated by using the elastic force model, and the good agreement with the experimental results has been obtained. The C_ (2D) 2D_2 C_ (2) HD_ (13) H_2 isotope products are also discussed.
