Document Summary
Goal: to understand how to use experimental spectroscopic data, together with information about atomic composition and electron configurations, to infer atom connectivity in molecular compounds. How ions are bonded to each other in molecules, or how ions are arranged around each other in ionic networks, will affect the distribution of electrical charges in the system. Molecular compounds are comprised of molecules, molecules are comprised of atoms. When two atoms get in close proximity of each other, the electrostatic attraction between the electrons located between the atoms, and the protons in each of the atomic nuclei leads to a net attractive force between the atoms. The strength of the attraction continues to increase as the molecules get closer together, until they reach a point in which the repulsive attractions begin to dominate. The equilibrium between attractive and repulsive attractions is the bond length .
