Purpose

This module holds a collection of our units and conversion factors. We use Angstroms (Å), eVs, and femtoseconds (fs).

Length:

Angstroms $= \mathrm{a.u.} \times \mathtt{Bohr}$

Energy:

eV $= \mathrm{a.u.} \times \mathtt{Hartree}$

Time:

fs

Mass:

$E T^2 / L^2 = \mathrm{a.u.} \times \mathtt{Hartree} \times \mathtt{AU\_fs}^2 / \mathtt{Bohr}^2$
