Question

Question No. 8
If a molecule has a center of
symmetry, then it is Raman
inactive.
Answer
A. O True
B. O False
​

Answer 1

Answer:

answer is false

Explanation:

If a molecule has a center of symmetry, Raman active vibrations would not be visible in the infrared.

Answer 2

If a molecule has a center of symmetry, then it is Raman inactive.:True

Explanation:

• If a molecule has a center of symmetry, then it is Raman Inactive.
• Symmetric mode vibrations give rise to Raman scattering.
• Raman Spectroscopy is used in various applications such as API concentration, powder purity, etc.
• Homonuclear diatomic molecules are IR inactive because there is no change in the dipole moment when it vibrates.
• Heteronuclear molecules are IR active because there is a change in dipole moment while vibrating.
