IR Spectroscopy
A technique used in chemistry to identify molecular structures based on the absorption of infrared radiation, which causes vibrational and rotational transitions in molecules.
IR Absorptions
The process by which molecules absorb specific frequencies of infrared light, causing transitions in their vibrational energy levels, useful for molecular identification.
Structure
Refers to the arrangement of atoms within a molecule, including their spatial orientation and any form of bonding or connectivity between them.
C≡C Stretch
