Sentence examples for sum of bond from inspiring English sources
The number of "incident pi bonds" is the sum of bond orders of explicitly connected atoms minus the "explicit degree".
Nevertheless, the rule to conform to the SMILES specification remains the same: square brackets are used if the total sum of bond orders is not equal to the standard valence.
Introduction of two amines on the pyridine ring enhances the electron-donating ability of the ligands (Scheme 10) which has also been indicated through crystal structure of complexes (17, 20, 23), and the sum of angles around nitrogen of N-heterocycle is 353° 360° (for example, the sum of bond angles in complex 20 = 360°, Fig. 5) which reveals sp2 hybridization of N-atom.
Non polar and internal energy contributions, which come from the sum of bond, angle and dihedral energies, constitute a small part of the enthalpy.
Valence sum rule: The sum of bond valences around any atom should be equal to the atomic valence, (eq 5).
Therefore if the bond valence, s ij, is set equal to the bond flux, the sum of bond valences around any ion, i, is equal to its valence, V i.
And while you can pay $30 to buy $10,000 worth of, say, Boeing stock, ordering a like sum of bonds could generate a markup of $300.
Total potential energy of system U is expressed as a sum of bonding energies for all pairs of atoms forming this system.
Total potential energy of system U is expressed as a sum of bonding energies for all pairs of atoms forming this system U={displaystyle sum_i{displaystyle sum_{j> i}left[{V}_Rleft({r}_{i j}right -{B}_{i j}right -{B}_{i}_{i j}^{V}_Rleftt]}} (3).
The oxidation state is evaluated as a round off value of the positive and negative sums of bond valences calculated with Equation (2)] from bond distances dCuI in Ref. [ 37] and RCuI=2.188 Å obtained from parameters in Ref. [ 35].
The respective formula for each of these cases is: carbon H = 4 - |C| - U - B. nitrogen and phosphorus: H = 3 - C - U - B. oxygen and sulfur: H = 2 - C - U - B. where C is the formal charge, U is the number of unpaired electrons standing in lieu of bonds, and B is the sum of the bond orders of neighbouring atoms.
