Bond overlap population
WebMar 3, 2014 · The electron-transfer path is investigated using the bond overlap population (BOP) analysis [20] between C atoms. In general, bond overlap itself is often used to … WebBond order index (overlap population) for UniBond is calculated as sum of bond order (overlap population) between atoms from first fragment and atoms from second fragment. You can choose/change all the options and Chemissian will update "on fly" the left window space where the calculation result is presented.

WebApr 21, 2024 · The overlap population is >0 for a bonding molecular orbital, <0 for an antibonding molecular orbital, and 0 for a nonbonding molecular orbital. It is convenient to tabulate these populations in matrix form for each molecular orbital. Such a matrix is … http://chemistry.uoguelph.ca/educmat/chm710/files/3_1_Overlap%20Populations.pdf
One problem with this approach is the equal division of the off-diagonal terms between the two basis functions. This leads to charge separations in molecules that are exaggerated. In a modified Mulliken population analysis, this problem can be reduced by dividing the overlap populations between the corresponding orbital populations and in the ratio between the latter. This choice, although still arbitrary, relates the partitioning in some way to the electronegativity difference bet…
