Vibrational Spectroscopy: Fundamentals of IR and Raman

Understanding how molecules absorb or scatter light provides powerful insights into their structure and composition. Vibrational spectroscopy is the essential technique used across chemistry and materials science for making these atomic-level observations. By the end of this course, you will be able to interpret complex IR and Raman spectra, understand the theoretical basis for molecular vibration, and apply these techniques to solve chemical identification problems. What you'll learn: * Understand the physics behind molecular vibrations, selection rules, and the fundamental differences between IR absorption and Raman scattering. * Master the interpretation of characteristic group frequencies in both infrared and Raman spectra for structural elucidation. * Learn the basic instrumentation and operational principles used for collecting high-quality vibrational data, including Fourier Transform techniques. * Apply foundational concepts of molecular symmetry and group theory to predict which vibrational modes are spectroscopically active. * Practice systematic analysis techniques to correlate structural features of molecules with observed spectral patterns. This course begins with the quantum mechanical foundation of molecular vibrations and progresses through practical spectral interpretation. We cover the operational principles of modern instruments and methods for qualitative analysis. This course is designed for absolute beginners in chemistry, physics, or materials science who need a foundational understanding of molecular analysis techniques. No prior knowledge of spectroscopy is required. Start reading today and unlock the secrets held within molecular vibrations.
