Question

23. The Raman and IR spectra can tell us whether : (a) a moleule is linear or non linear (b) a molecule is symmetrical or asymmetrical (c) neither of the above (d) Both (a) and (b)​

Answer 1

Answer:

D

Explanation:

raman spectroscopy is a non destructive interaction between molecular arrangements where it can interact with bond between atoms and gives structure symmetry and arrangements

Answer 2

1. Raman spectra are produced by light scattering by vibrating molecules, whereas IR spectra are produced by light absorption by vibrating molecules.
2. Raman activity is caused by a change in a molecule's polarizability, whereas IR activity is caused by a change in dipole moment.
3. The Raman and IR spectra can tell us whether,

• a molecule is linear or non-linear,
• a molecule is symmetrical or asymmetrical

Hence, option D is correct.
