The results of electrostatic calculations of the lattice energies of crystals formed from linear hydrogen-bonded chains of HCN molecules are reported. Two types of crystal structures are considered: one in which the chains are aligned with their dipole moments parallel, and the second where alternat
The microwave spectrum of the heterodimer EKYbMF is reported, the collinearity of the nuclei establislIed, and ro(N--F) = 2.796 A obtained. From the Stark effect, ~10 (tiCN4iF) = 5.59 r 0.02 D which indicates an enhancement of 0.78 D over the vector sum of the monomer values.
