Unlocking the Secrets of Matter: A Guide to the Fundamentals of Spectroscopy
Have you ever wondered how scientists determine the structure of a molecule, identify an unknown substance, or track the speed of a chemical reaction? The answer often lies in spectroscopy—the powerful scientific technique that studies the interaction between light and matter. This 12-week journey into the fundamentals of spectroscopy will equip you with the core principles to understand this essential field in chemistry, physics, and biology.
What is Spectroscopy?
At its heart, spectroscopy is the investigation of how matter absorbs, emits, or scatters electromagnetic radiation (light). Light encompasses a vast spectrum, from high-energy gamma rays to low-energy radio waves. By probing a sample with specific wavelengths and analyzing how it responds, we can extract a wealth of information.
This course will show you how different spectroscopic techniques act like unique diagnostic tools:
- Rotational Spectroscopy reveals bond lengths and molecular shapes by examining how molecules rotate.
- Vibrational Spectroscopy (like IR) probes the strength of chemical bonds by studying how atoms vibrate.
- Electronic Spectroscopy explores the energy levels of electrons, crucial for understanding color and reactivity.
- Raman Spectroscopy provides complementary vibrational information by analyzing scattered light.
Beyond structure, spectroscopy is a key analytical tool for quantification and, because each transition happens on a specific timescale, a window into ultrafast molecular dynamics.
Meet Your Expert Instructors
This conceptual foundation is built by two distinguished scientists who bridge cutting-edge research and clear pedagogy.
Prof. Sayan Bagchi (NCL Pune & AcSIR)
Prof. Bagchi brings a deep experimental perspective. After his Ph.D. from the University of Pennsylvania and postdoctoral research at Stanford University, he joined the CSIR-National Chemical Laboratory (NCL) in Pune. His research focuses on using novel spectroscopic techniques to unravel molecular interactions and dynamics. With over six years of teaching experience in spectroscopy, he excels at translating complex experimental concepts for students.
Dr. Anirban Hazra (IISER Pune)
Dr. Hazra provides the crucial theoretical framework. A specialist in theoretical chemistry from Princeton University, his research at IISER Pune delves into excited state phenomena where the Born-Oppenheimer approximation breaks down. Using advanced computational methods, his work helps explain the mechanistic chemistry that spectroscopy reveals. This combination of theoretical and experimental viewpoints is a unique strength of the course.
