Raman Spectroscopy
Raman spectroscopy is a technique used in chemistry to study the vibrational, rotational, and low-frequency modes of molecules. In this technique, monochromatic radiation is used to study the properties of the molecules.
Statement Analysis
Statement 1: In this spectroscopy, polychromatic radiations are used to study the properties of the molecules.
This statement is incorrect. In Raman spectroscopy, monochromatic radiation is used, not polychromatic radiation.
Statement 2: It is used to study the vibrational, rotational, and low-frequency modes of the molecules.
This statement is correct. Raman spectroscopy is primarily used to study the vibrational modes of molecules. It can also be used to study rotational and low-frequency modes.
Therefore, the correct answer is option B: 2 only.

Recently, Scientists from the Centre for Nano and Soft Matter Sciences (CeNS), an autonomous institute of the Department of Science & Technology (DST), Govt. of India, have designed an efficient SERS substrate.
- It was discovered by C.V. Raman in 1928 to study the vibrational, rotational, and low-frequency modes of the molecules.
- Principle: The principle behind Raman spectroscopy is that the monochromatic radiation is passed through the sample such that the radiation may get reflected, absorbed, or scattered.
- The scattered photons have a different frequency from the incident photon as the vibration and rotational properties vary.
- Types of Raman Spectroscopy are
- Resonance Raman Spectroscopy (RRS)
- Surface-enhanced Raman Spectroscopy (SERS)
- Micro-Raman Spectroscopy
Hence only statement 2 is correct.
