Abstract

This study adopts the improved model Pὂschl-Teller potential to examine the internal vibration of three diatomic molecules. The analytical expressions that predicted molar enthalpy, heat capacity and molar Gibbs free energy were obtained. Using the various molar predicted equations, numerical values for enthalpy, heat capacity and Gibbs free energy were generated for fluorine molecule, iodine molecule, chlorine molecule, phosphorus molecule and potassium molecule. A model equation to check the proximity of the predicted results to the experimental data was obtained. This equation was used to obtain the average absolute percentage deviation of the predicted result from the observed data recorded in National Institute of Standards and Technology data base. The results for all the molecules exhibit remarkable consistency with the observed data.

与一类改进P - schl-Teller势相互作用的三种模型的热力学函数预测
本文采用改进的P - schl-Teller势模型来研究三种双原子分子的内部振动。得到了预测摩尔焓、热容和摩尔吉布斯自由能的解析表达式。利用各种摩尔预测方程,得到了氟分子、碘分子、氯分子、磷分子和钾分子的焓、热容和吉布斯自由能的数值。建立了模型方程,验证了预测结果与实验数据的接近性。该方程用于从美国国家标准技术研究院数据库中记录的观测数据中获得预测结果的平均绝对百分比偏差。所有分子的结果与观测数据表现出显著的一致性。
