Fraunhofer line	Joseph Fraunhofer		Absorption line in the spectrum of the Sun, studied by Fraunhofer in 1814. The nine most prominent he labeled with capital letters (from the red end) A. B. C. D. E. F. G. H. and K. The A band and B band are now known to be groups of telluric lines due to O2 absorption in Earth's atmosphere, and C and F are respectively known as Hα and Hβ.	1814	Sun	absorption line		emission line
molecular band		molecule	A series of closely spaced, often unresolved, emission or absorption lines found in the spectra of molecules. Each line represents an increment of energy due to a change in the rotational state of the molecule.			set of molecular lines
B band	Joseph Fraunhofer	O2	Telluric lines due to O2 absorption in Earth's atmosphere, but originally thought to originate in the Sun by Fraunhofer.	1814	Earth's atmosphere	Fraunhofer line	7100 Å	emission line
