where h is the reduced Plank's constant, [[omega].sub.H] is the proton magnetogyric ratio and Larmor frequency, respectively, [r.sub.ij] is the internuclear distance, and [[tau].sub.c] is the effective correlation time which modulates the i-j magnetic interaction.
The differences among the Cu-F bonds can be entirely attributed to the different Cu-F internuclear distances: as Cu-F lengthens, [[rho].sub.b], [[nabla].sup.2][[rho].sub.b], and [[lambda].sub.3b] decrease in absolute value.
Based on the relationship between NOE and internuclear distances, one can give the expression of distance in each conformer
Halogen bonding reduces internuclear distances up to twenty percent as compared to the all Van der waals distances [20].
(ii) the homo- and heteronuclear dipolar interactions, which are spatial in nature and related to the internuclear distances. (iii) the scalar through bond J interaction, which is characteristic for chemical bonding between nuclei.
The derived molecular properties, such as rotational and centrifugal distortion constants, hyperfine structure constants, electric dipole moments, rotational g-factors and internuclear distances (for diatomic molecules) are listed with one standard deviation uncertainties for all species.
