Subject	has specie	is a kind of	has definition
molecular band	molecule	set of molecular lines	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.
telluric lines	O2, H2O, or CO2	molecular band	Spectral lines or bands that originate from absorption by gases such as O2, H2O, or CO2 in the Earth's atmosphere.
