Of particular relevance to the present work are the cc-pVnZ-PP-F12 basis sets for the heavy p-block elements Ga-Kr, In-Xe, and Tl-Rn. 26 These basis sets are constructed for use with the Stuttgart-Cologne small-core relativistic pseudopotentials (PPs), and although PPs are used for all of the heavy p-block elements, the simple abbreviation VnZ-F12 is used to refer to these sets herein.
