Spectroscopy is an analytical technique that measures the interaction between electromagnetic radiation (or other energetic probes, such as electrons or ions) and matter as a function of wavelength, frequency, or energy to obtain information about a system’s composition, structure, and dynamics. By monitoring absorption, emission, scattering, or reflection, spectroscopy reveals quantized energy levels associated with electronic, vibrational, and rotational states. Variants such as UV–Vis, infrared, Raman, nuclear magnetic resonance, and X-ray spectroscopy exploit distinct interaction mechanisms and selection rules, enabling determination of molecular identity, chemical environment, bonding characteristics, and in some cases spatial or temporal evolution of materials and biochemical systems.

When we think about a diamond, we often think about a material whose value comes from its perfection. In my research, however, I am interested in something almost opposite: the tiny imperfections inside diamonds. These atomic-scale ...
For highly fragile quantum information systems, the ability to store quantum information is vital—but also challenging. Quantum information is transported in particles of light called photons, which often must be temporarily ...

In a new Physical Review Letters study, researchers have demonstrated that bending diamond nanostructures can tune the light they emit without doping.
Astronomers have cataloged billions of stars and hundreds of billions of galaxies. We have found thousands of planets orbiting stars. We can also map where galaxies sit and trace how the universe changes over time.

Across every cell in the body, molecules are constantly pulling, gripping and releasing under mechanical strain. That force often decides whether a drug sticks to its target, whether a cell holds its shape or whether a disease ...
