This directory contains basis sets of TZV (triple zeta valence) quality as described in A. Schaefer, C. Huber, R. Ahlrichs: J. Chem. Phys. 100 (1994) 5829 The basis sets have TZ quality in the valence region and are highly contracted in inner shells in order to reach maximum efficiency. NOTE: There has been an error in the the TZ basis for ar (file /pub/basis/ar) which is corrected now. If you have got the SV/DZ/TZ basis sets before May 1993 please download the updated version.
