Ricc2 / Re: cc2 triplet excitation energies
« Last post by Arnim on June 14, 2017, 10:38:55 am »
Hi Evgeniy,

I don't think there is a general recommendation, but the recipe is quite simple. Take for a start really huge cbasis and then remove functions (or optimise them with the cbasopt script) while monitoring the errors.

In your case, I would say you could set up a small model system and start with the aug-cc-pV5Z cbasis, then go down to aug-cc-pVQZ and aug-cc-pVTZ. If the error with the TZ with respect to the 5Z is acceptable, then you are done.

Hope that helps,


Escf and Egrad / Temperature of Raman scatt. cross sections
« Last post by Punix on June 09, 2017, 09:34:59 am »
Dear TM users,

Is there a way to manipulate the vibrational temperature of your Raman scatt. cross sections in the intense program. It automatically prints them out at 298.15 K and of course I can recalculate them for a different T myself but I was just wondering if there might be a command or addition of something to the program that would already do that.

the module which does IRC is called DRC. To get its options (especially the one to use IRC) please just call

DRC -h

on the command line. Basically all you have to do is to start DRC in the directory where you have successfully optimized your transition state and checked with a frequency calculation that you are at the TS.

Hi Arnim,

Many thanks for your reply. In relation to my question, I wonder if there is
a  well-defined and reliable recipe  what cbas is to use in general if there
is no optimized cbas for a particular basis set. For example, for Pople's
basis sets, like 6-311++G**.

Best regards,

Hello everyone

It's me again!! I have another question

How Can I perfom an IRC calculation in turbomole?

Thanks in advance

Hi Evgeniy,

actually for now (version 7.1) there are no optimized cbasis sets for the dhf-series.
For some elements the dhf are equal to def2. In these cases the def2-cbas can be chosen, but in the other cases not.
Then you could try the def2-TZVPP or def2-QZVPP cbasis. But do some convergence tests on smaller model systems to ensure the performance.


Define / No cc-pVDZ-PP auxiliary basis for Iridium
« Last post by evgeniy on June 01, 2017, 01:46:39 pm »

I was surprised that for Iridium (Ir) there is no cc-pVDZ-PP auxiliary basis, whereas there is the
(larger) cc-pVTZ-PP one. I am curious what is the reason of the absence of the cc-pVDZ-PP?

Dear Arnim,

I am interested in adc(2) excited state calculations with account for spin-orbit coupling, using ecp with a 2-c basis.
I wonder what auxiliary basis set is to choose in the case of 2c (dhf-SVP) "main" basis?

Best regards,
Aoforce and Numforce / $maxcor in distributed parallel aoforce calculation
« Last post by Jerry on May 30, 2017, 12:06:19 pm »
I am running an aoforce calculation on 48 cores distributed over several nodes with $maxcor=2000.  In this case, does $maxcor correspond to memory per core (total memory = 48*2000MB) or to the total memory for the calculation?

Best regards,

TURBOMOLE Forum General / scratch folders are deleted
« Last post by tigger10 on May 18, 2017, 06:56:25 am »
I have a question about scratch folder
I'd set $tmpdir and $sharetmpdir as,

$tmpdir /scratch/jaewook/
$sharetmpdir /scratch/jaewook/

and I made a folder /scratch/jaewook/
After the calculation is ended, that folder disappeared.
Do turbomole programs erase that folder?
