Definitions:

Alkene Absorption

Refers to the specific wavelengths at which alkenes absorb infrared light due to the stretching vibrations of the carbon-carbon double bond.

Stretching Frequency

A measure of how often a chemical bond undergoes a vibration between atoms, used in IR spectroscopy to help identify functional groups.

IR Spectroscopy

A technique used in chemistry to identify molecules based on the absorption of infrared radiation at different wavelengths.

IR Spectroscopy
