The spectrometer works best in darkness ... on the camera's right-side field of view. If using the hydrogen source, be sure to aim the camera at the red part of the excited gas. Turn off the lamp when ...

Researchers have observed hydrogen and deuterium molecules in tiny spaces called picocavities using advanced spectroscopy. This study reveals unique differences between the molecules due to quantum ...

Different chemical structures absorb light at specific ... of the FTIR spectrometer, which cannot monitor chemicals that are infrared inactive like dinitrogen, oxygen and hydrogen,” said Dr ...

In this study, the researchers used a newly developed high-energy resolution X-ray spectroscopy technique at the Inner-Shell Spectroscopy (ISS) beamline at the National Synchrotron Light Source II ...
