*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 ...

NMR (Nuclear Magnetic Resonance) spectroscopy is a powerful analytical technique that provides detailed information about the structure, dynamics, and chemical environment of molecules at the atomic ...

Photons in the ultraviolet/visible spectral range have sufficient energy to ionize or excite materials by increasing the energy level of bound electrons. NIR radiation has less energy per photon but ...

Astronomers study planetary transits and atmospheric signals using interstellar object 3I/ATLAS, drawing on transit spectroscopy principles and recent observational constraints discussed by Avi Loeb.
