Abstract:

The experimental design of quantitative research on the absolute hardness of compounds in Hard and Soft Acid and Base (HSAB) rule using Gaussian software is introduced, which involves geometry optimization and high-level single point energy calculation. Through the experiment, students will grasp basic steps of using quantum chemistry to calculate the absolute hardness, deepen their understanding of the theory of HSAB, and lay the foundation for future research work.

Key words: HSAB, Computational chemistry experiment, Absolute hardness, Density functional theory
