Definitions:

IR Absorption

The process by which molecules absorb infrared radiation at specific wavelengths corresponding to vibrations of molecular bonds.

Characteristic IR Stretches

Characteristic Infrared (IR) Stretches are specific absorption bands in IR spectroscopy that correspond to the vibrations of molecular bonds, helping to identify functional groups within a molecule.

C≡C Stretch

A vibrational mode observed in infrared spectroscopy, characteristic of the stretching of a carbon-carbon triple bond.

C=C Stretching

A vibrational movement in infrared spectroscopy, where the carbon-carbon double bond length changes, useful in identifying unsaturated compounds.
