Türkçe soru sormak isteyenler, yorum kısmında türkçe soru sorabilirler. Benim için bir problem değil. Sakın çekinmeyin. Asıl çekinen benim ya cevaplıyamazsam diye...

Ayrıca Türkçe sorun oğlum, salayın gitsin ne olacak. Herkes anlayacak diye bi kural yok. Türkler burada torpillidir.

Surface enhanced raman spectroscopy is an important technique to increase the Raman intensity. When light hits roughened metal surfaces (typically gold, silver, or copper nanoparticles), it excites localized surface plasmons. These plasmons create an intense local electromagnetic field, which amplifies the Raman scattering of molecules nearby. When a molecule interacts directly with the metal surface, charge transfer between the molecule and metal can further increase the Raman cross-section.
SERS is more useful than Raman because it:

Provides much stronger signals

Allows detection of ultra-low concentrations

Can suppress fluorescence interference

Enables applications like single-molecule studies and biosensing

Today I learned something new, surface plasmon
A surface plasmon is a collective oscillation of free electrons that occurs at the interface between a metal (or a material with free electrons) and a dielectric material (like air or water). Imagine the electrons on the surface of a metal oscillating together in response to an external electric field, such as from light. These oscillations are quantized as plasmons.

There are two main types:

Surface Plasmon Polaritons: These are propagating waves that travel along a planar metal-dielectric interface.

Localized Surface Plasmons: These occur in metallic nanoparticles. When light interacts with these nanoparticles, it can excite coherent, confined oscillations of the electrons within the particle. These localized surface plasmons generate very strong, localized electromagnetic fields near the nanoparticle's surface.

I realized a small mistake in the CO MO diagram on one of my video. Instead of the 2s orbital, I wrote 1s orbital. I am sorry for that mistake. If you think that there is a mistake in my videos, you can use comment section to show my mistake.
