Modified form of atomic force microscopy gives chemical signature of molecules. Our experimental findings are corroborated by ab initio density functional theory calculations. The molecule tetrahedrene shown below is an example of a stretched double bond that ultimately splits into a lower energy form, namely, a di-carbene. Monograph and Report Series, Number Three. Examples of recent theoretical studies include computation of the structure and properties of heterocyclic carbenes using ab initio and Density Functional Methodology (DFT). Molecular orbitals are then expanded in terms of atomic orbitals as linear combination of atomic orbitals (LCAO). Over the past decade they have developed several high resolution microcalorimeters which allow accurate determination of the binding energies of different atoms and molecules to specific surfaces. One of the hot topics at the workshop I attended was the proper role of "first principles" calculations in trying to understand electronic conduction at the atomic and molecular scale. Unitivity Theory, A Theory of Everything. We have computed There is evidence for significant aromatic stabilization if at least two nitrogen atoms are part of the pi system in the ring. These results present a significant challenge/ benchmark for electronic structure methods (such as density functional theory) which claim to be able to calculate accurately such quantities.
