Hello;

	I got the following values for polarizability of water
	with different basis sets ( HF method):

	sto-3g                        0.274 (A')^3
        6-31G*                        0.467
        6-31G**                       0.479
        6-31+G**                      0.608

	Exp.                          1.47
                                      1.45

	Can anyone please tell me why these calculated values
	are so much far from experimental data?

	Many thanks in advance,
	Mansoor
