The bond distance and angles are consistent with results of the in situ X-ray absorption spectroscopy (XAS) studies of Cu(I)-Cl and Cu(I)-HS complexes [6,12,32].
That is, the vector of the molecular dipole is given by [delta].r, being [delta] partial atomic charge and r the bond distance (Figure 1).
The 1-2 and 4 binuclear core showed a Rh-Rh bond distance in an expected range of 2.3925(6), 2.3886(5), and 2.3860(6) A, respectively (see Figures 5(a)-7(a) and Table 3) [68-70].
HG1 atom of Thr310 has interacted with O13 atom of the ligand with a bond distance of 2.2 [Angstrom].
are considered to be 1.68794 [[Angstrom].sup.2], 0.453456 [[Angstrom].sup.4], and 0.22682 [[Angstrom].sup.4], respectively, and the covalent bond distance of the carbon atoms is 0.142nm [25].
Table 1: Key geometry parameters for the ground states of cis- and trans-SP forms as well as the corresponding mode compounds (bond distance in angstroms and dihedral angles in deg).
Stability and affinity complex of the active side with ligand is influenced by the bond distance. This indicates that the ARTS ligand form conformation that can change the conformation or in other words can inhibit hemin.
Typically, the Si=Si double bond distance and the SiSiSi bond angle of trisilaallene 34a are 2.183(1) [Angstrom] and 136.49(6)[degrees], which are in good accord with the values calculated theoretically; they are 2.230 [Angstrom] and 130.2[degrees] at the B3LYP/6-31G(d) level, (42) and 2.230 [Angstrom] and 135.7[degrees] at the BP86/TZVPP level.
Steine (2002) showed a correlation between the vOH frequency and hydrogen bond distance [22], where the frequencies shown by the zinc compound, 3500 [cm.sup.-1] and 2853 [cm.sup.-1] can be correlated with the hydrogen bond distances 2.77 [Angstrom] and 2.59 [Angstrom] respectively, with a good agreement.
The reactive group oxygen (OAI) of lupeol hydrogen bonded with the backbone hydrogen of Val 135 with a bond distance of 1.93 A units.
The coating protects the tool against abrasion, adhesion, diffusion, formation of comb cracks and other wear due to the high strength of their covalent inter-atomic bond, small bond distance, high coordination number and its Vickers hardness HV of 40-60 and >70 GPa (Veprek et al 2003).
