WebOther articles where band spectrum is discussed: spectrum: Band spectra is the name given to groups of lines so closely spaced that each group appears to be a band—e.g., nitrogen spectrum. Band spectra, or molecular spectra, are produced by molecules radiating their rotational or vibrational energies, or both simultaneously. WebThe remaining elements in the periodic table, including those essential for the molecules in our bodies, were then created in stars through nucleosynthesis before the earth was formed. One of the strongest pieces of evidence for the theory of stellar nucleosynthesis is the observation of absorption lines of the element Technetium from distant stars.
