Definitions:

IR Stretch

Infrared stretching refers to the vibration that occurs between atoms within molecules as they absorb infrared radiation, indicative of functional groups in a compound.

IR Bond Stretches

Refers to changes in bond lengths within molecules as observed in infrared spectroscopy, indicative of various functional groups.

Wavenumber

A measure of the frequency of a vibration or a wave, often used in spectroscopy, expressed as the number of waves per unit distance.

IR Absorption

The process where a molecule absorbs infrared light, leading to an increase in vibrational energy levels, used in infrared spectroscopy to identify functional groups within a molecule.
