— http://www.molpro.net
— A user mailing list is available under
http://www.molpro.net/mailman/listinfo/molpro-user/?portal=
user&choice=User+mailing+list
— In molpro, the emphasis is given to highly accurate computations,
with extensive treatment of the electron correlation problem through
the multiconfiguration-reference CI and coupled cluster methods.

Running molpro
— Molpro is accessed using the molpro command. The syntax is:
molpro [options] [datafile]
— datafile is the input. Prepare your input with .com extension.
— output will be written to a datafile.out file
— -d dir1:dir2:…
where dir1:dir2:… is a list of directories which may be used
for creating scratch files.
— There are more options…
— Molpro can be run in parallel:
-n specifies the number of cpu
-N specifies the number of tasks on the node

Electron correlation methods
— Hartree-Fock is a single determinant wave function method where molecular orbitals are varied.
— Configuration Interaction (CI) is a multiple determinant wavefunction method where molecular
orbitals are not varied.
— CI wavefunction is constructed by starting with the HF wavefunction and making new determinants by
promoting electrons from the occupied to unoccupied orbitals.
— Depending on the number of excitations used to make the determinants, CI methods are called CIS,
CISD, CISDT, CISDTQ and full CI.
— Multi-configurational self-consistent field (MCSCF) calculations also use multiple determinants. In
contrast to the CI, orbitals are also optimized.
— An MCSCF calculation in which all combinations of the active space orbitals are included is called a
complete active space self-consistent field (CASSCF) calculation.
Turbomole

Electron correlation methods
— In a CASSCF wavefunction the occupied orbital space is divided into a set of inactive or closed-shell
orbitals and a set of active orbitals. All inactive orbitals are doubly occupied in each Slater determinant.
On the other hand, the active orbitals have varying occupations, and all possible Slater determinants
(or CSFs) are taken into account which can be generated by distributing the Nact=Nel-2mclosed electrons
in all possible ways among the active orbitals, where mclosed is the number of closed-shell (inactive)
orbitals, and Nel is the total number of electrons.
— It is possible to construct a CI wavefunction starting with an MCSCF calculation rather than starting with
a HF wavefunction. This starting wavefunction is called the reference state. These calculations are
called multi-reference configuration interaction (MRCI).
— Coupled cluster (CC) calculations are similar to CI calculations in that the wavefunction is a linear
combination of many determinants. The means for choosing the determinants in CC is more complex than
CI. There are variants of CC: CCSD, CCSDT and CCSD(T).

Density fitting
— Density fitting can be used to approximate the integrals in spin restricted
Hartree-Fock (HF), density functional theory (KS), second-order Møller-Plesset
perturbation theory (MP2 and RMP2), explicitly correlated MP2 (MP2-F12), and all levels
of closed-shell local correlation methods (LCC2, LMP2-LMP4, LQCISD(T), LCCSD(T)).
— Density fitting is invoked by adding the prefix DF- to the command name, e.g. DF-HF,
DF-KS, DF-MP2 and so on.
— Symmetry is not implemented for density fitting programs.
— By default, a fitting basis set will be chosen automatically that corresponds to the current
orbital basis set and is appropriate for the method. For instance, if the orbital basis set is
VTZ, the default fitting basis is VTZ/JKFIT for DF-HF or DF-KS, and VTZ/MP2FIT for
DF-MP2.
— Examples:
BASIS=VTZ
DF-HF,DF_BASIS=VQZ
DF-MP2,DF_BASIS=VQZ

Spin component scaled (SCS) MP2
— SCS-MP2 is based on a separate scaling of the second-order parallel
(αα+ββ) and antiparallel-spin (αβ) pair correlation energies e(2).
— The SCS-MP2 approximation to the correlation energy Ecorr is given by
— Here, pT and pS are empirical parameters determined to be 1/3 and 6/5.
— If you perform an MP2 calculation, you already have the SCS-MP2 energy.
