In the work by Parker et al. (TM Parker, LA Burns, RM Parrish, AG Ryno, CD Sherril, J. Chem. Phys… 2014, 140(9), 094106. DOI: 10.1063/1.4867135), some levels of SAPT are discussed (recommended as the gold, silver, and bronze standard of SAPT: SAPT2+(3)δMP2/aug-cc-pVTZ, SAPT2+/aug-cc-pVDZ, and sSAPT0/jun-ccpVDZ).
Could someone with experience suggest me some SAPT levels to calculate the interaction energy of dimer halogenated molecules derived from methane (e.g., CH3F, CH2F2, CF4, CFCl3…etc)?
Calculations with sSAPT0/jun-ccpVDZ (bronze standard) were successful (did not crash). I tried to perform calculations with SAPT2+/aug-cc-pVDZ (silver standard) but they always crashed because temporary files generated were too large.
I would like to know if there is any better level than sSAPT0/jun-ccpVDZ for calculating the interaction energy of halogenated dimers derived from methane.
Any suggestions or references are welcome.
