- As an aside to the several recent messages on the wavelengths of
- microwaves and of various types of transitions in water molecules, it
- should be realized that an applied signal does _not_ have to be in
- resonance with, or anywhere near the resonance frequency or transition
- frequency of an atom or molecule, to cause observable losses.
-
- The small absorption losses or weak absorption coefficients in many
- "transparent" materials at various frequencies in fact come from the
- long-wavelength tails of very strong absorption lines at much, much
- shorter wavelengths or much higher transition frequencies.
-
- I don't actually know what causes the microwave-frequency absorption
- of liquid water, however...
