Lecture
This lecture covers the fundamentals of optical spectroscopy, including the study of the interaction between radiation and matter, the measurement of signal intensity as a function of energy, and the importance of optical spectroscopy in various fields such as semiconductors, astronomy, and remote sensing. It delves into the principles of spectroscopy techniques like infrared and UV-VIS, explaining their limitations and applications. The lecture also explores the design and operation of spectrometers, including prism and grating spectrometers, and the concept of resolvance in Fourier Transform Infrared (FTIR) spectrometers.
