About the Book:

This book is the Seventeen Objective Physical Chemistry Primer of the Chem Sparrow Chemistry Primers of Chem Sparrow Publications. This book is concerned with the Physical Photochemistry: Electronic transitions in molecules. The Franck Condon principle. Electronically excited molecules- singlet and triplet states. Radiative lifetimes of excited states-theoretical treatment. Measured lifetimes. Quantum yield and its determination. Actinometry-ferrioxalate and uranyl oxalate actinometers-problems. Derivation of fluorescence and phosphorescence quantum yields. E-type delayed fluorescence evaluation of triplet energy splitting (∆E_ST). Photophysical processes-photophysical kinetics of unimolecular reactions. Calculation of rate constants of various photophysical processes problems, State diagrams Photochemical primary processes. Types of photochemical reactions- electron transfer, photodissociation, addition, abstraction, oxidation and isomerization reactions with examples. Effect of light intensity on the rates of photochemical reactions. Photosensitization. Quenching-Stern Volmer equation. Experimental set up of a photochemical reaction. Introduction to fast reactions- Principle of flash photolysis. This textbook is a genuine attempt to provide sufficient information for the student to be able to attempt their end-semester and several competitive examinations. In this book totally we are covered 32 Solved Objective Physical Photochemistry Questions of various competitive examinations.

This book is designed from the basic level to the advanced level of Physical Photochemistry, and this book is particularly designed for all competitive examinations in India from IIT-JEE, and NEET examinations to CSIR-UGC-NET and GATE examinations. It will be useful for faculty and students and researchers. This book is useful for NEET, IIT-JEE, IIT-JAM, CSIR-UGC-NET, GATE, all state-level P.G. Entrance examinations, All State-level Eligibility Tests (SET Exams), All State-Level Research Eligibility Tests (RCETS) and All-Central-Level Public Service Commission Examinations (UPSC), All-State-Level Public Service Commission Examinations which are related to Chemistry.

The textbook is divided into one unit, the first unit covers APPSC Chemistry previous year solved objective questions. The way the subject matter is presented prevents students from memorizing by rote. In fact, the subject has been organized around the Physical Photochemistry: Electronic transitions in molecules. The Franck Condon principle. Electronically excited molecules- singlet and triplet states. Radiative lifetimes of excited states-theoretical treatment. Measured lifetimes. Quantum yield and its determination. Actinometry-ferrioxalate and uranyl oxalate actinometers-problems. Derivation of fluorescence and phosphorescence quantum yields. E-type delayed fluorescence evaluation of triplet energy splitting (∆E_ST). Photophysical processes-photophysical kinetics of unimolecular reactions. Calculation of rate constants of various photophysical processes problems, State diagrams Photochemical primary processes. Types of photochemical reactions- electron transfer, photodissociation, addition, abstraction, oxidation and isomerization reactions with examples. Effect of light intensity on the rates of photochemical reactions. Photosensitization. Quenching-Stern Volmer equation. Experimental set up of a photochemical reaction. Introduction to fast reactions- Principle of flash photolysis. Students will quickly be able to predict much of what will happen after mastering these rules and principles. The text is well-illustrated with examples from the surrounding world to make the qualitative and quantitative components of the subject easier to understand.

The completion of this book has been possible with the valuable insights and critical feedback from several individuals, and we express our sincere gratitude to Team-Chem Sparrow for his invaluable contributions. Through this Objective Physical Chemistry primer, Chem Sparrow Publications continues its commitment to advancing the understanding of Objective Physical Chemistry. We hope this textbook not only aids in academic success but also inspires curiosity and innovation in the study of Physical Photochemistry.
