Quantum Mechanical Conformational Analysis of ��-Alaninemide Dipeptide

Bio molecules are crucial molecular components of biological systems that are responsible for various functions. These functionalities are intimately linked to their conformational preferences. Conformational analysis of N-acetyl N'-methyl ?-alanineamide using multidimensional conformation analysis (MDCA) and potential energy scan (PES) techniques are studied in this book. This book consists of four chapters. Chapter 1 provides a brief introduction to the theoretical methods used and the molecular systems studied in this thesis.Chapter 2 provides a short overview of the theoretical methods employed in the current work. A concise explanation of the density functional theory (DFT) moller-plesset perturbation theory (MP2) implicit solvation method (mainly polarizable continuum model (PCM)) and molecular tailoring approach (MTA) techniques are presented here. In Chapter 3 various ab initio calculations using the density-functional (DFT) the second order Moller–Plesset perturbation (MP2) and self-consistent reaction field (SCRF). In Chapter 4 conclusion has given.
