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 ...

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 ...

The difficulty stems from a fundamental tradeoff when performing THz measurements: achieving high spectral resolution versus high spatial resolution. To accurately capture the narrow spectral ...

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