Question

which spectra is due to change in polarizability of the molecule​

Answer 1

Answer:

Raman spectroscopy

Raman spectroscopy occurs as a result of a molecular vibration causing a "change in polarizability" of the molecule.

.

Answer 2

vibrational Raman spectrum.

vibrational Raman spectrum is due to change in polarizability of the molecule​

• The relative propensity of a charge distribution, such as the electron cloud of a molecule, to be deformed from its natural shape by an external electric field, such as that present in an electromagnetic wave, is known as polarizability. A molecule is Raman active if its polarizability shifts while it is vibrating.
• A molecule becomes less polarizable as its electron density, bond strength, and bond length all increase.
• Vibrational Raman spectroscopy is the name given to the spectroscopic method based on Raman scattering in which the molecules change their vibrational state. The distinct and finely resolved vibrational signature of the scattering molecule can be found in a vibrational Raman spectrum.
• The following are some ways that polarizability impacts dispersion forces: The dispersion forces get stronger when polarizability goes up. As a result, molecules have a stronger attraction to one another, and covalent compounds' melting and boiling temperatures rise with increasing molecular mass.
