water lines

(spectral lines specific to water)

Water lines (spectral lines) in astrophysics fall under at least two classifications:

Water absorption, like that of many compounds, produces many lines affecting significant bands of the spectrum,

The presence of water vapor in extra-solar planet atmospheres can be detected by transmission spectroscopy through recognizable water lines. Water's presence in Earth's atmosphere significantly limits microwave observations from the ground, motivating observations from space as well as from high, dry ground locations.
