 | 5 | DESCRIPTION
 | 
|---|
 | 6 | ===========
 | 
|---|
 | 7 | 
 | 
|---|
 | 8 |   MPQC computes the properties of molecules, ab initio, on a wide variety of
 | 
|---|
 | 9 | computer architectures.
 | 
|---|
 | 10 | 
 | 
|---|
 | 11 |   MPQC can compute closed shell and general restricted open shell
 | 
|---|
 | 12 | Hartree-Fock energies and gradients, density functional theory energies and
 | 
|---|
 | 13 | gradients, second order open shell perturbation theory (OPT2[2]) and
 | 
|---|
 | 14 | Z-averaged perturbation theory (ZAPT2) energies, and second order closed
 | 
|---|
 | 15 | shell Moeller-Plesset perturbation theory (MP2) energies and gradients.
 | 
|---|
 | 16 | Closed shell energies using (ABS) MP2-R12 are also supported.  It also
 | 
|---|
 | 17 | includes an internal coordinate geometry optimizer.
 | 
|---|
 | 18 | 
 | 
|---|
 | 19 |   MPQC runs on Unix compatible workstations, symmetric multi-processors,
 | 
|---|
 | 20 | and parallel computers.
