Newguy:
for those who understand technical stuff

Donaldwfc:
Thanks

gail3logan:
What basically is water polarizability? Can you explain?

Newguy:
polarizability to me basicaly means  what conditions needs to be met to become polarized.

Newguy:
heres sum more useless knowledge i guess lol:
 
The polarizability is also frequency-dependent; we consider here the high-frequency (electronic) value and the low-frequency (static) limit.
The latter includes not only the response of the electrons to an applied field but also a vibrational contribution from the response of the
atoms in the molecule. For the mean electronic polarizability, we adopt the value 1.457(3)×10-30 m3, which Russell and Spackman [12] extracted
from refractive index data. For the vibrational contribution to the total polarizability in the low-frequency limit, we adopt the estimate of
Bishop and Cheung [13], which is 0.037×10-30 m3. The uncertainty in the vibrational contribution is probably on the order of ten percent [13].
For the mean total dipole polarizability (in the static limit), which is the sum of the electronic and vibrational effects, we therefore adopt
a value of 1.494(7)×10-30 m3.
