Dual-Comb Spectroscopy Used to Improve Spectral Resolution

The optical frequency comb (OFC), which is similar to a comb (or rule) in optical frequency, offers equidistant comb lines across a wide bandwidth. Each comb line corresponds to an absolute optical frequency.

How X-Ray Helical Dichroism Helps to Detect and Separate Enantiomers

Scientists can now identify mirror-image molecules more easily, thanks to a new technique. This is crucial for drug development among other things since the two types might have quite different impacts on the human body. In the academic journal Nature Photonics, researchers from the Paul Scherrer Institute PSI, EPF Lausanne (EPFL), and the University of Geneva present the innovative technique.

Researchers Measure Atmospheric Water Vapor Using Open-Air Spectroscopy

Researchers demonstrated that a new mid-infrared spectrometer can accurately quantify the ratios of different kinds of water—referred to as isotopologues—in atmospheric water vapor in less than 15 minutes via open air. Isotopologue ratios, which can be influenced by land-based water evaporation and plant transpiration, are used to create climate change models and to better comprehend how water moves around the world in the atmosphere.
