රසායනික බන්ධන විවිධ පරිමාණ වලින් - Computational ව්‍යාපෘතියක් කරමු Let's do a computational chemistry project using OpenMM (39:42) How do chemists understand a chemical bond? Molecular orbital theory helps us understand this. If you haven't watched the previous videos you can check it out here: 1. Quantum Vs Classical mechanics - https://youtu.be/EsRlDKCi2EM 2. What is a chemical bond? https://youtu.be/oERFHqewf_A Many thanks to Dulitha Prasanna for joining the podcast to talk about Quantum Mechanics. 00:00 Mathematics of molecular orbital theory 03:39 Molecular orbital diagrams 05:09 Contribution of each orbitals 06:46 Intro to GAMESS (Practical example) 09:42 Input file (for Nitrogen) 18:30 Visualizing molecular orbitals 22:24 Our understanding of bonding 23:18 Calculations and output file 25:41 Anti-bonding orbitals 27:40 Benzene rings 29:02 Dipeptide hydrolysis 30:51 Computational range/length 33:31 Classical mechanics 36:31 Experiments Vs Simulations 39:06 Course-grained, mesoscale 39:42 OpenMM Python package 45:30 Interaction in solvent box 47:11 Using super computing clusters 49:43 Future projects (Fundraiser)
