Above are the spectral lines of Xenon(Xe). The Emission band of Xenon is pretty dense and the wavelengths range from between 350 and 1100 nm, with a large band centered at 550 nm and two strong bands at 820 and 880 nm wavelength.

Above are the Spectral Lines of Krypton(Kr). In appearance, Krypton is a colorless gas, exhibiting a whitish glow in an electric field, but in Spectrometer Krypton is characterized by several sharp emission lines (spectral signatures) the strongest being green and yellow.

Above are the Spectral Lines of Oxygen(O). In appearance, Oxygen is very dull and doesn’t emit much light in an electric field. Spectrum Tubes filled with Oxygen gas are characterized as not being very bright. However it is one of the most important gas for the planet earth. Major Spectral lines of oxygen are with wavelengths of 558 nm (green) and 630 nm (red).

Above are the Spectral Lines of Element Sodium(Na). It is dominated by the bright doublet known as the Sodium D-lines at 588.9950 and 589.5924 nanometers Wavelength.

Above are the Spectral Lines of Element Argon(Ar). In pure argon, the brightest lines, in order of intensity, are those at 811.5 nm, 763 nm, and 750.4 nm. The most peaks are present for argon at the wavelengths (696.54, 706.72, 750.38, 763.51, 800.61, 810.36, and 912.29 nm).

Above are the Spectral Lines of Element Carbon(C). When electric current is passed through the gas, the discharge emits bluish glow.

One of the Brightest glowing gases. Above are the spectral lines of Neon(Ne). The wavelengths range from 400 nm on the left (violet) to 750 nm on the right (red).

Above are the Spectral Lines of Mercury Vapor(Hg). The wavelengths of the prominent lines in mercury are purple (405 nm), blue (436 nm), blue- green (492 nm), greenish yellow (546 nm), yellow (577 nm), orange (623 nm), and red (691 nm).

Above are the Spectral Lines of Nitrogen(N2). The spectrum generated by nitrogen ranges from 300 nm to 400 nm, and the light emitted by ionized nitrogen molecules can be clearly seen at 337 nm and 358 nm.

Above are the Spectral Lines of Sulfur/Sulphur(S). The mass spectrum of sulfur vapor has been measured by evaporating sulfur from a heated tube directly into the ionization chamber of a mass spectrometer.
