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 ...

Hot gases don’t produce a continuous emission spectrum. Black hydrogen absorption lines are at the same wavelength as the bright hydrogen emission lines. Key fact Line emission spectra are ...

For the first time, EPFL researchers have exclusively observed molecules participating in hydrogen ... spectrum. These ultra-short bursts of light create tiny charge oscillations and atomic ...

Moreover, the model was able to explain the hydrogen atom’s spectral lines ... providing a coherent explanation for atomic stability, spectral lines, and the interaction between electrons ...
