Brief Program Description

TURBOMOLE consists of a set of programs for carrying out DFT and ab initio MP2 calculations for closed- and open-shell molecules and evaluating magnetic and other molecular properties. It has a variety of built-in basis sets. The most important feature of TURBOMOLE is its ability to evaluate integrals very efficiently and thus achieve very fast execution times. This is done by using auxiliary basis sets for main row atoms and transition metals to approximate Coulomb potentials and is coined the RI method (ie. RIMP2, RIDFT).

The set of programs currently available are listed in the documentation. These support the evaluation of energies, gradients, second derivatives, a number of first-order properties and NMR chemical shieldings at the MP2 level. The program's capabilities are:

• Single point calculations

• Geometry optimisations

• Calculations of molecular properties

• Calculations involving solvent incorporation

• Effective Core Potentials

New features in TURBOMOLE 6.0.1 include:

• N^4 spin scaling SOS-RI-MP2 (module ricc2)

• Faster MP2-F12 (module ricc2)

• (One-electron) transition moments between excited states in CC2

• Douglas-Kroll-Hess Energies in C1

Note that MoleControl has not been implemented on Magellan.

Areas of Application

• The program is especially well suited for large DFT and MP2 calculations which take advantage of the efficiency of the RI method provided.

• Calculation of spectroscopic properties of large molecules.

Implementation and Access

TURBOMOLE 6.1 is available on Magellan. This version runs in serial and in parallel. Access is via the $CHEM/runturbo61 command. The interactive scripts needed to set up the input files are available on Magellan, located in the $CHEM/turbomole6.1/TURBOMOLE/scripts directory. For details and examples on how to use TURBOMOLE 6.1, please see the man page by typing: man runturbo61

The previous versions 6.0.1 and 5.10 are still available on Magellan and runs in serial and in parallel. Access is via the $CHEM/runturbo601 and $CHEM/runturbo510 commands. The interactive scripts needed to set up the input files are available on Magellan, located in the $CHEM/turbomole6.0.1/TURBOMOLE/scripts and $CHEM/turbomole5.10/TURBOMOLE/scripts directories. For details and examples on how to use TURBOMOLE 6.0.1 and 5.10, please see the man page by typing: man runturbo601 and man runturbo510 respectively.

Please note that TURBOMOLE 5.9.1 is still the default version on Magellan.

Machines

Available on Magellan.

Documentation

The TURBOMOLE User Manual is available from the TURBOMOLE web site, and also online in PostScript format in the directory $CHEM/doc/turbomole . Example structure files are provided in the directory $CHEM/doc/turbomole/structures . There is a Unix-style man page available containing information on the local implementation of TURBOMOLE, accessible by typing: man runturbo61 .

For TURBOMOLE versions 6.0.1 and 5.10, the corresponding man pages are accessible by typing: man runturbo601 and man runturbo510 respectively.
