Since the first demonstration of the laser in the 1960s, laser spectroscopy has become an essential tool for studying the detailed structures and dynamics of atoms and molecules. Advances in laser ...

A gap-controlled infrared technique makes it possible to study molecular interfaces with high sensitivity using affordable, widely available lab equipment. These molecular interfaces are everywhere—on ...

Researchers have shown how spectroscopic measurements can be made much faster. By correlating polarization to the color of a pulsed laser, the team can track changes in the spectrum of the light by ...

The explosive growth of electric vehicles, renewable energy integration, and large-scale energy storage systems has placed ...

Why 3,000 bars are needed to take a comprehensive look at a protein: Researchers present a new high-pressure spectroscopy method to unravel the properties of proteins' native structures. A pressure of ...

Using the shrink-assembled liquid 3D hot spot matrix as a microreactor, a new method for quantitative detection of blood drug concentration by surface-enhanced Raman spectroscopy (SERS) was ...

Elemental spectroscopy is a method employed to examine in-service fluid samples such as engine oil or hydraulic fluid, to determine the presence and quantity of different substances. This approach ...

Dynamics Author: Howard Goldner During the past few decades, fluorescence spectroscopy has developed into an integral technique in many scientific disciplines. In the life sciences, it is implemented ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Freeform dual comb spectroscopy creates images of methane plumes not visible to the human eye. Dual comb advance: Esther Baumann works in the lab at NIST. Scientists at the U.S. National Institute of ...
