Study Notes
Spectroscopic Methods
- The main principle underlying every spectroscopic method is the interaction between matter and electromagnetic radiation.
Molecular Excitation
- When a molecule becomes excited in the spectroscopic process, it absorbs energy and transitions to a higher energy state.
Spectroscopic Process
- The step that involves bombarding the molecule with photons of various frequencies is called irradiation.
Photon Detection
- Detecting re-emitted photons in the spectroscopic process is significant because it provides information about the molecular structure and properties.
NMR Spectroscopy
- Nuclear magnetic resonance (NMR) spectroscopy is associated with the electromagnetic phenomenon of nuclear shielding.
