IT is usually considered that molecular hydrogen does not have an infra-red rotation-vibration spectrum. However, such a spectrum may be expected as a forbidden transition made possible by the ...

The light from each star is directed through a prism to produce a spectrum. Each of the spectra has a set of absorption lines created by the presence of hydrogen in the stars' atmospheres.

When a gas is very hot, it doesn’t emit all wavelengths of light. Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the ...

Nonetheless, existing solar hydrogen production technologies face limitations in absorbing light across this broad spectrum, particularly failing to harness the potential of near infrared (NIR ...

Hydrogen bonds result when hydrogen ... laser pulses in the near-infrared spectrum. These ultra-short bursts of light create tiny charge oscillations and atomic displacements in the water, which ...
