The hydrogen spectrum is particularly important because 90% of the normal matter in the universe is hydrogen. Because of the details of hydrogen’s atomic structure, ...

Spectrum of normal hydrogen taken at room temperature and 1000 psi pressure after background removal. Image Credit: Thermo Fisher Scientific. Conclusion. This study demonstrates that Raman ...

From analogy with other spectra, Rydberg further calculated the positions of lines which Would constitute the Principal series of hydrogen, and the first line, at 4687.88, has been identified with ...

Astronomers have now observed the radio emission from the neutral hydrogen gas (HI) in a nearby galaxy. Hydrogen gas emits radio emission in a spectral line at a very specific frequency of 1420 MHz.

I'm writing up a report about 21cm-line radio astronomy, and it includes a discussion of spectral lines and the 21cm line in particular.However, I have a problem that I was hoping the genius of ...

No hydrogen is found in its spectrum. Calcium, oxygen, and silicon appear in its spectrum at peak brightness. This type of supernova is seen in all types of galaxies.

The spectra of type Ic supernovae not only lacks hydrogen, but it also lacks helium. This is because, prior to exploding, type Ic supernovae are thought to lose more of their initial envelope than ...
