    • - anion or the allyl anion as a suitable reference. In these molecules the charge of the terminal atoms is 1.5, as that of the central atom 1 s or π electron. In the system O⋯H⋯N the charges should be about 1.60, 1, and 1.4 electrons in view of the electronegativity difference. Hence, a charge transfer of 0.4 electron from lp2(O) into the σ*(NH) orbital at an appropriate distance R(O,H) should lead to covalent bonding. Using this value as reference one obtains the percentages given in the text. Note that the one-orbital contributions always contain the repolarization effect, thus making an estimate of the covalent effect difficult.
