Terahertz (THz) radiation, which occupies the frequency band between microwaves and infrared light, is essential in many next ...

Spectroscopists are often required to identify an unknown compound from a measured spectrum, verifying sample integrity, and defining detected impurities in a sample. Performing a spectral search can ...

The new approach produces extremely accurate and stable frequencies and could significantly enhance precision timekeeping and high-resolution atomic and molecular spectroscopy. WASHINGTON — ...

Researchers have developed a new smaller, lighter design for space-based imaging spectrometers with high spectral resolution. These high-dispersion imaging spectrometers could be used onboard ...
