In 1974, the first enhanced Raman spectrum was experimentally observed in pyridine adsorbed onto a roughened Ag electrode,1 which was then correctly interpreted in 1977 to be an enhancement in the efficiency of Raman scattering itself on the surface of substrates.2 Since then, materials that serve...

Stimulated Raman scattering 8.1.1 Raman-gain spectrum In a simple approach valid under the CW or quasi-CW conditions, the initial growth of the Stokes wave is described by [6] (8.1.1)dIsdz=gRIpIs, where Is is the Stokes intensity, Ip is the pump intensity, and the Raman-gain coefficien...

When an incident photon interacts with a crystal lattice or molecule, it can be scattered either elastically or inelastically. Predominantly, light is elastically scattered (i.e.the energy of the scattered photon is equal to that of the incident photon). This type of scattering is often refer...
Because both A1 and A2 have out-of-plane components in the vibration patterns, they exhibit strong spin-dependent Raman scattering as their out-of-plane vibration components are coupled with the out-of-plane magnetic order in CrI3. As shown in Eq. (3), above the Curie temperature where the...
The Raman polarizability densities distributed within the red sphere are locally enhanced by the near field leading to the effective scattering polarizability densities, which are then integrated over all space to obtain Raman intensity that corresponds to the specific tip position recorded in the TERS ...

used Raman spectroscopy to assess brain edema, by measuring the water concentration in the tissue directly.118 Karabeber et al. evaluated the ability of a handheld Raman scanner, guided by surface-enhanced Raman scattering (SERS) nanoparticles, to identify the microscopic tumor extent in a mouse ...
Graphene-enhanced Raman scattering (GERS) on isotopically labelled bilayer and a single layer of pristine and partially hydrogenated graphene has been studied. The hydrogenated graphene sample showed a change in relative intensities of Raman bands of Rhodamine 6 G (R6G) with different vibrational en...
