Quick Example
Consider that you want to calculate the electronic energy of a methane molecule. First, you will need the cartesian coordinates of the molecule of interest. This information is stored in our methane.xyz
file, formatted as follows:
5

methane = molecule("methane.xyz")
For any molecular calculations, you will need a basis set.
sto3g = buildbasis(methane)
With this information, we can build the molecular integrals.
S = overlap(sto3g, methane)
T = kinetic(sto3g, methane)
V = attraction(sto3g, methane)
G = repulsion(sto3g, methane)
