Definitions:

Characteristic Stretching

The unique vibration of molecular bonds within a molecule, used in infrared spectroscopy to identify specific functional groups.

Frequency

The number of cycles or vibrations per unit of time; in physics and chemistry, it often relates to the energy levels of atoms and molecules.

Least Intense

Describes the weakest signal or effect in a set of data or spectral analysis, often indicative of low concentration or sensitivity.

Stretches

In spectroscopy, refers to the vibrational movements (stretching and bending) of molecular bonds that are studied to identify functional groups in molecules.
