Physical chemistry deals with the study of the behavior of matter on a molecular and atomic stage and how chemical reactions take place. Based on their analyses, physical chemists may develop new theories, like how complex structures are formed. This book provides an extensive coverage of the topics discussed in physical chemistry. This book opens with an attempt at addressing this limitation with a specific periodic table for chemistry. Following the introduction of the new even-odd and isoelectronic rules and definitions affecting the understanding of electronic structure and bonds, the author has thought necessary to summarize understandings in the form of a table. The classical periodic table, a simple tool used by generations of physicists, is here extended to become a useful tool aimed specifically at chemists. Further, the book focuses on enhancement of electrochemical performance of bilirubin oxidase modified gas diffusion biocathode by porphyrin precursor. Further, it explores the chemical synthesis of nitrogen-doped titanium dioxide (N-TiO2) in an attempt to understand the mechanisms of doping. The effect of doping on band gap, morphology, and microstructure was also determined. This book succeedingly focuses on controlled release kinetics in hydroxy double salts and hydrogen bonding interaction between atmospheric gaseous amides and methanol. Additionally, it also focuses on photochemical reactions of Microcystin-LR following irradiation with UV Light. Following with synthesis and study of electrical properties of SbTeI, the book finally highlights on magnetic isotope effect, which can be used to predict the mechanisms of chemical reactions.
