Abstract:
An algebraic Hamiltonian for the two coupled nonlinear vibrations of highly excited nonrigid molecule HCP was presented. The Hamiltonian reduces to the conventional one in a limit which was expressed in terms of harmonic oscillator operators. It showed that the algebraic model can better reproduce the data than the conventional model by fitting the observed data of HCP.

摘要:
提出一种研究非刚性HCP分子的高激发非线性振动的代数哈米 顿量,它在极限条件下退化为传统的用谐振子算子表示的模型,拟合 观测的实验数据表明,代数模型比传统模型较好地描述了这些数据.
