Dear all,
 Is there anyone who knows why dipole moments calcultaed with a 6-31++G** basis
 set are worser (deviate more from experimental values) than those calculated
 with a 6-31G* basis set?
 I used B3LYP as calculation method and I tested it for 10 molecules.
 Thank you in advance for help,
 Best regards, Goedele
