*If you learn how to use atomic absorption spectroscopy (AAS), you can do accurate and reliable chemical research. But it takes practice and concentration to fully grasp its basic ideas. Understanding ...

AES operates on the principle of the Auger effect, named after the French physicist Pierre Auger. When a material's surface is bombarded with a beam of high-energy electrons or photons, it causes the ...

X-ray photoelectron spectroscopy is based on the same principle as all photoelectron spectroscopy methods. If a molecule or material is irradiated with light of a known energy above the ionization ...

Raman spectroscopy is a reliable quantitative and qualitative technique used to examine molecular or material samples. Raman spectroscopy’s sensitivity to a sample’s vibrational structure makes it ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...

Spectrofluorometer is an instrument that works on the principle of fluorescence spectroscopy. It is a rapid and sensitive method for the characterization of molecular components present in a sample.
