Water does have Raman scattering, but it is relatively weaker compared to other materials due to its symmetric molecular structure and low Raman cross-section. This makes it more challenging to detect and study using Raman spectroscopy.

The Raman effect, also known as Raman scattering, is the inelastic scattering of a photon. It was discovered by C. V. Raman and K. S. Kishnan in liquids. G. Landsberg and L. I. Mandelstam discovered it in crystals.

Raman scattering and Rayleigh scattering are both types of light scattering, but they differ in how they interact with molecules. Rayleigh scattering occurs when light interacts with particles smaller than the wavelength of light, causing the light to scatter in all directions. Raman scattering, on the other hand, involves a change in the energy of the scattered light due to interactions with molecular vibrations. This results in a shift in the wavelength of the scattered light, providing information about the molecular structure of the material.

Yes, there are different types of Raman spectroscopy, including spontaneous Raman spectroscopy, surface-enhanced Raman spectroscopy (SERS), and resonance Raman spectroscopy. Each type utilizes different methods to enhance the Raman scattering signal and provide insights into different sample properties.

The Raman effect is the inelastic scattering of light by molecules, resulting in a shift in wavelength. Fluorescence is the emission of light by a substance that has absorbed light or other electromagnetic radiation. Both phenomena involve interactions between light and molecules but differ in the mechanism of light emission.

Raman active molecules are those that exhibit a change in polarizability during the Raman spectroscopy process. This change results in the scattering of light at different wavelengths, providing information about the molecular structure and vibrations of the molecule. Raman spectroscopy is a powerful technique used for chemical analysis and identification.

Yes, Raman effect or, more usually, Raman scattering, is indeed supported by the quantum theory of light. Raman scattering is the inelastic scattering of light (photons) off matter, and it is included in quantum theory. Most photons scatter elastically, and Rayleigh scattering explains this. But a tiny fraction of photons come away from a scattering event at the same energy as they entered it. Raman described this effect in liquids, and Landsberg and Mandelstam later described it in crystals.
One of the curiosities of quantum theory is that it has been modified over the years as new information has been presented. It was a good theory in its inception, and the basic tenants remain at its foundation. But as with any effective explanation of the way things work, it has been "expanded" to encompass the later discoveries that more clearly detailed and refined what it says. Why would it not have been?

The Raman effect refers to the inelastic scattering of light by molecules, resulting in a change in energy of the scattered photons. This effect provides information about the vibrational and rotational modes of molecules, making it a useful tool for analyzing chemical structures and compositions. Raman spectroscopy is a common technique that utilizes the Raman effect for various applications in chemistry, physics, and materials science.

Raman spectroscopy measures the scattering of light, while FTIR spectroscopy measures the absorption of infrared light. Raman spectroscopy is better for analyzing crystalline materials, while FTIR is more suitable for identifying functional groups in organic compounds. Additionally, Raman spectroscopy is less sensitive to water interference compared to FTIR spectroscopy.
1 answer
Raman spectroscopy is based on the inelastic scattering of light, where photons interacting with a sample undergo energy exchange, resulting in shifts in wavelength that can be used to identify molecular vibrations. By analyzing these shifts, information about molecular composition and structure can be obtained.

Polarized Raman spectra refer to Raman scattering measurements where the incident and scattered light are polarized along specific directions. By using different polarization configurations, researchers can gather additional information about the orientation and symmetry of molecular vibrations in the sample. This technique is useful for studying anisotropic materials and understanding molecular structure and orientation.

Metals have the ability to shield external electric field, therefore when laser light used for excitation in Raman spectroscopy falls on the metal surface, it cannot penetrate very deeply.
Also, noble metals have crystal structures with only one atom per unit cell, therefore only acoustic phonons exist, and no optic phonons that could be detected with Raman. Exceptioon is gallium - see ref.

Essentially Raman spectroscopy focuses incident light upon a target. The photons of the incident light can scatter elastically or inelastically upon striking the molecules of the target molecule. Either way, the dipole moments of the molecules involved are temporarily increased and energy is emitted.

In the Raman effect, a photon is scattered inelastically (meaning it has a different, lower, energy after scattering than before) from an atom or molecule, causing excitation, i.e., raising an electron to a higher energy level.
In the Compton effect, a photon is scattered inelastically from an atom or molecule, causing ionization, i.e., ejecting an electron from the atom or molecule.
