The calculated bond lengths, bond angles and dihedral angles for Schiff-base were using the semi-empirical (PM3, AM1 and MNDO) methods at geometry optimization (0.001 Kcal / mol), Table-4.
Another anomaly is the bond lengths measured between carbon atoms in benzene.
In this equation, K, T, and [DELTA]L stand for the Boltzmann constant, the absolute temperature, and the bond length change, respectively.
As a result of the structural scan and geometry optimization, we have found that, in Figure 2(a), the equilibrium bond length in singlet state of [Si.sub.2][H.sub.6] cluster model is 2.34 [Angstrom], similar to the ordinary Si-Si bond length of 2.36 [Angstrom] [31].
The bond length at the glued end of the specimen examined varied from 0 to 200 mm at this stage (Figure 6(a)).
The bond lengths, dihedral angles, energy gaps, frontier molecular orbitals, electron injection, and recombination of the optimized molecules were calculated.
where N is the number of bonds taken into calculation, [R.sub.av] is the averaged bond length, [R.sub.av] = 1/n[[summation].sup.n.sub.i=1][R.sub.i], and [R.sub.i] is the virtual bond length calculated from the Pauling bond number [29] [n.sub.i] = exp(R(1 - R(n)/c).
Such an observation corroborates the increment observed in [O.sub.1]-[H.sub.1] bond length due to the substitution of the H atom.
The C-C and C-H bond lengths are 1.76 [Angstrom] and 1.09 [Angstrom], respectively, which is consistent with previous research [27].
(ii) Based on the DFT, a series of first principle calculations have been performed on the relaxation, the bond length, and the overlap population of Sn[O.sub.2] surface.
According to the model, if the bond length is sufficient then the bond-slip relation for that region does not vary along the bonded area, whereas if the bond length is not sufficient then the bond-slip relation varies with the location.
