Question

What would one use to find out how the atoms in a molecule are oriented in three-dimensional space?

Answer 1

we need to use QTAIM(quantum theory of atoms in molecules).electron density distribution of a molecule is the probability distribution which describes how electronic charge is distributed in 3D space.QTAIM is a model of of molecular electronic system where atoms and bonds of molecular structure are expressions of system's observable electron density distribution function.we can find the molecular structure by stationary points of electron density with the gradient path of probability density that originates and terminates at the point.
