Also of interest is that H2O absorbs energy at 190, 200, 250,
300, and 400 nm wavelengths.
Do you have a reference for these UV lines ?
BTW the main cosmological frequencies used to spot water are the
H2O vapor absorption peaks at around 180 GHz and 320 GHz and there
is also strong microwave absorption of water at around 22 GHz.
This later one is not a simple rotational transition but it is the
most used by cosmologists, I have read, as the others are out of
range of inexpensive precision instrumentation.
