Nelson et al. (Science 238, 1670 (1987)) examined several weakly bound gas-phase complexes of ammonia in search of examples in which the H atoms in NH3 formed hydrogen bonds, but found none. For example, they found that the complex of NH3 and CO2 has the carbon atom nearest the nitrogen (299 pm away): the CO2 molecule is at right angles to the C–N ‘bond’, and the H atoms of NH3 are pointing away from the CO2. The magnitude of the permanent dipole moment of this complex is reported as 1.77 D. If the N and C atoms are the centres of the negative and positive charge distributions, respectively, what is the magnitude of those partial charges (as multiples of e)?arrow_forward
