CM211IA Unit 5 Molecular Topological Indices Part 3/4

Molecular Topology | Topological Indices | Zagreb Index | Wiener Index | Platt Number In this recorded lecture, I introduce topological indices in molecular topology, which are numerical descriptors derived from molecular graphs and widely used in computational chemistry and molecular modelling. The lecture explains how molecular structure and connectivity can be quantified using topological indices for predicting physicochemical properties and biological activity. The session covers three important and commonly used indices: Zagreb indices – degree-based descriptors related to molecular branching Wiener index – distance-based index representing overall molecular compactness Platt number – measure of molecular branching based on edge adjacency These indices play a crucial role in QSAR/QSPR studies, cheminformatics, drug design, materials science, and nanotechnology, enabling structure–property and structure–activity correlations. 📌 Topics Covered: Introduction to Molecular Topology Concept of Topological Indices Zagreb Index (First and Second) Wiener Index Platt Number Applications of Topological Indices in QSAR/QSPR 🎯 Target Audience: Undergraduate and postgraduate students Engineering Chemistry & Materials Science students Beginners in molecular modelling and computational chemistry 🔍 Keywords: Molecular Topology, Topological Indices, Zagreb Index, Wiener Index, Platt Number, Molecular Graph Theory, QSAR, QSPR, Cheminformatics, Computational Chemistry Lecture
