Module 1: FUNDAMENTALS OF SPECTROSCOPY. It’s amazing how much we can learn about molecules and materials by shining light on them! In spectroscopy, we use light to determine a tremendous range of molecular properties, including electronic, vibrational, rotational, and electron and nuclear spin states and energies.

Jul 10, 2024 · Introduction to spectroscopy. 2 comments. Bookmark. Explain the principles of a range of spectroscopic techniques including infrared (IR), ultraviolet-visible (UV-vis) and nuclear magnetic resonance (NMR). Each technique has clear explanations and descriptions supported by animations (many of which are interactive) to aid your learning.
We can divide spectroscopy into two broad classes of techniques. In one class of techniques there is a transfer of energy between the photon and the sample. Table \(\PageIndex{1}\) provides a list of several representative examples.
Oct 12, 2020 · 1. To learn how light absorption and emission are observed. 2. To learn to operate and make measurements using a simple spectrometer and a spectrophotometer.
Spectroscopy is the study of the interaction of light and matter. Many types of spectroscopy rely on the ability of atoms and molecules to absorb or emit electromagnetic (EM) radiation. The absorption or emission of different forms of EM radiation is related to different types of transitions.
