IR Spectroscopy

Introduction to the topic of Infrared spectroscopy:-

• Use the micro-lecture on Infrared spectroscopy (IR) to explain what happens when a molecule is exposed to IR radiation.
• Explain that a molecule absorbs IR energy when the frequency of stretching or bending of the molecular bonds corresponds to that of the incident IR light.
• Use this video to explain the basic working of an IR spectrometer that is used to obtain the IR spectra for known/unknown molecules.
• Further, with the help of the video, briefly explain how the functional groups present in a molecule can be deduced by examining its IR spectrum.
