Diploma in Molecular Interactions

Subject description :This paper deals with some of the basic features in molecular
interactions.
Goals: To make the students familiar with chemical bonding and interaction between the
molecules.
Objectives: Students should be able to interpret the interaction between molecules.UNIT-I
Fundamentals of atomic and molecular orbitals:
Theory of atomic and molecular orbitals; Linear combination of atomic orbitals;
Quantitative treatment of valency bond theory and molecular orbital theory; Resonance
structures; s-bonds and p-bonds.
UNIT-II
Fundamentals of chemical bonding and non-bonding interactions:
Electrovalent bond, stability of electrovalent bond. Co- valent bond - partial ionic
character of co-valent bonds. Shape of orbitals and hybridization. Co-ordination bond,
Vander Waals forces; Metallic bond. Molecular geometry- VSEPR Theory.
UNIT-III
Folding pathways: Principles of protein folding, hydrophobic interactions,
electrostatic interactions, non-bonded interactions. Beta turns, gamma turns, types
of helices, disulphide bridge.
UNIT -IV
Molecular interactions: protein-protein, protein-DNA, DNA-Drug, Protein-
Lipid, Protein-Ligand, Protein-Carbohydrate interaction, Metalloproteins, Pi ... Pi
interactions, C-H...Pi interactions.
UNIT-V
Spectroscopy: Principles, Theory, Instrumentation and Application of UV,
IR, NMR and Circular dichroism (CD) to macro molecules.
