2O>TMEDA. The fact that theoretical gas phase calculations do not take association effects into account is a possible explanation of the large discrepancy between the literature and theoretical values for HMPA. The theoretical dipole moment for water was found to be 1.36 D as opposed to a value of 1.84 D in the literature. This illustrates that hydrogen bonding effects are not taken into consideration in the theoretical gas phase calculations
