They made calculations of electron density using density functional theory (DFT) and realised that these differences could be revealing bond order. For example benzene which has 6 C atom and 6 H atom. Unitivity Theory, A Theory of Everything. DFT thinks it is too complicated to calculate and consider single electrone wave functions on every calculation. NBO terminology and general mathematical formulations for atoms and polyatomic species are presented. If I can make in mathematical term, it looks like: Total=aA+bB+cC+… where a is coefficient for atom or molecule A (applied to b, c, and d .. Density-Functional Theory of Atoms and Molecules. The outcome of this result is that To corroborate the experimental findings and gain further insight into the exact nature of the contrast mechanisms, the team performed first-principles density functional theory calculations. Monograph and Report Series, Number Three. Density Functional Theory (DFT), and post-HF computations. EU funding has helped realise a scientific first; using a technique known as non-contact atomic force microscopy (AFM), scientists have successfully been able to differentiate the chemical bonds in individual molecules. For atom or molecule B, C, and D) and A is the atomic orbital or molecular orbital of A structure.
