Gaussian Tutorial (Lec-13) Transition State Calculation in Gaussian 16 | TS Guess Method
Ref: https://www.science.org/doi/10.1126/s... In this tutorial, we perform a transition state (TS) calculation for the HCN → HNC isomerization using Gaussian 16 and the TS Guess Method. The video covers: • Building the initial TS guess geometry • Transition state optimization in Gaussian 16 • Frequency analysis and imaginary frequency verification • Understanding the HCN ⇌ HNC rearrangement mechanism • Important tips for successful TS convergence Transition state calculations are essential in computational chemistry for studying reaction mechanisms and energy pathways. This example provides a simple and beginner-friendly introduction to TS optimization and analysis. Whether you're new to Gaussian or looking to refine your skills, these tutorials will guide you through practical examples, tips for using the interface, and insights into advanced calculations. Perfect for students, researchers, and anyone interested in computational chemistry!
