物理系统和分子的大多数性质都来自于其组成原子的性质和相互作用。这些相互作用的对称性提供了对所得性质的形式和质量的重要见解,例如极化率,偶极矩和弹性。为了更好地利用对称性作为科学中的一种工具,在这里,我们介绍了四种新的对称性分析方法,作为不规则粒子对称性分析软件(IPSA)的一部分。IPSA软件包提供了一个在一致结构下检查连续对称性和群论的框架,使人们能够独特地了解如何检查和量化原子结构的几何对称性。本文中提出的方法是实用的程序表征和低成本添加到现有的材料和分子性质的检查,具有广泛的应用范围,包括领域,如电子结构估计,计算简化,几何分类,动力学分析,光谱解释,和属性预测。
The majority of properties of physical systems and molecules are derived from the character and interaction of their constituent atoms. The symmetry of these interactions provides significant insight into the form and quality of resultant properties such as polarizability, dipole moments, and elasticity. In order to better utilise symmetry as a tool within science, here we introduce four novel methods of symmetry analysis as part of the Irregular Particle Symmetry Analysis software (IPSA). The IPSA software package presents a framework for examining continuous symmetry and group theory under a consistent structure, enabling a unique insight into how the geometric symmetry of atomic structures may be examined and quantified. The methods presented within this paper are practical procedures for characterisation and low-cost additions to existing examinations of materials and molecular properties with a wide range of applications, including areas such as electronic structure estimation, calculation simplification, geometry classification, analysis of dynamics, spectrographic interpretation, and property prediction.
