*ab initio* Cyclic Cluster Model
********************************
The *ab initio* Cyclic Cluster Model (AICCM) program is an object oriented,
**educational** quantum chemical code written in the Python scripting
language with C extensions. It depends on the `Atomic Simulation Environment (ASE)` for
calculation setup and makes heavy use of Python modules (NumPy, SciPy,
Matplotlib) and LAPACK routines. It is mainly developed by `Michael F. Peintinger `_
and `Thorsten Claff `_ at the `Mulliken Center for Theoretical Chemistry `_
at the University of Bonn (Germany). You can find a full list of contributors in the
development section.
The aim is to implement the Cyclic Cluster Model (CCM), which directly
applies periodic boundary conditions (PBC) to a finite free cluster
(corresponding to a non-primitive unit cell), at *ab initio* level.
Atomic Simulation Environment (ASE)
===================================
The `Atomic Simulation Environment (ASE) `_ provides Python modules for manipulating atoms, analyzing simulations and visualization and is interfaced by various
quantum chemical codes. AICCM is implemented as an ASE calculator.
