Gaussian Calculation, Optimization, and Result Analysis | Step-by-Step Tutorial

In this video, we’ll go through the complete workflow of Gaussian software — from setting up a calculation, performing geometry optimization, to analyzing the output results. You’ll learn how to interpret the energy values, optimized coordinates, molecular orbitals, and key spectroscopic data that help understand your compound’s behavior at the quantum level. 🧩 What You’ll Learn: ✅ How to prepare an input file in Gabedit or Gaussian ✅ Setting up optimization and frequency calculations ✅ Selecting suitable methods (DFT, HF, Semi-Empirical) and basis sets (6-31G(d,p), STO-3G, etc.) ✅ Running Gaussian calculations effectively ✅ Reading and analyzing Gaussian output files ✅ Extracting optimized energy, HOMO-LUMO gap, dipole moment, and bond parameters #cadd #Gaussian #Gaussian09 #Gaussian16 #Gabedit #GeometryOptimization #EnergyMinimization #DFTCalculation #QuantumChemistry #ComputationalChemistry #MolecularModeling #InSilicoLab #DrugDesign #CADD #HOMOLUMO #MolecularOrbitals #GaussianTutorial #DFTB3LYP #BasisSet #OptimizationResults #GaussianOutputAnalysis #GaussianSoftware #MoleculeOptimization #QuantumChemicalCalculations #ComputationalDrugDesign #ChemistryLearning #ResearchTutorial #Chemoinformatics #GaussianTraining #PharmacyResearch #InSilicoDrugDesign
