Question

What part of the atom or molecule does infrared radiation affect

a. the nucleus

b. the electrons

c. the bonds

d. the charge​

Answer 1

Answer:

the bond

Explanation:

infrared radiation is absorbed or emitted by the rotation and vibration of chemically bonded atoms or groups of atoms

Answer 2

Answer:

The bonds of a molecule are affected by infrared radiation.

Therefore, option (c) is correct.

Explanation:

Infrared Spectroscopy is a kind of spectroscopy that is used to characterize organic molecules by functional group. We use techniques to determine the functional groups present in a molecule.

• Infrared radiations induce molecular vibrations in the covalent bonds when they are being absorbed by molecules.
• Certain bonds will absorb at specific wavelengths of light, which will use to determine the strength of the bond and type of the functional groups are present in the molecule.
• A diatomic molecule on absorption with infrared light would causes stretching of the bond. The movement back and forth of each atom is called a stretching vibration.
• When bonds lengthen and shorten at the same extent, is known as symmetric stretching vibration. When one bond shortens and the other lengthens is known as asymmetric stretching.
• There are two kinds of bending vibrations which are scissoring and rocking.
