Hello...<div><br /></div><div>I am new to cp2k. I started with geometric optimization and partial charge calculation of MoS2 (hexagonal) and CdS (cubic) crystals (2*2*1 supercells for the time being) respectively. For charge calculation, I was using RESP fitting method. For MoS2, the fitting was good showing sufficiently low RRMSE (~ 0.09 - 0.1) and RMSE (~0.00005), respectively, and the fitted data matched with literature too. </div><div>Conversely, during the same exercise for CdS, inspite of achieving physically reasonable partial charges for both Cd (~ +2.00) and S (~ -2.00), the RRMSE (~ 0.98 - 0.99) and RMSE (~ 0.0008) came out to be extremely high. I wonder why this is happening in doing the similar exercise, despite using the similar PPs and Basis sets. I shall be highly obliged if anyone helps me out with this. I have attached my input files and the PPs and Basis sets used for both the cases below.</div><div><br /></div><div>Cd (PP): GTH-PBE-q12</div><div>Cd (BS): DZVP-MOLOPT-SR-GTH-q12</div><div>S (PP): GTH-PBE-q6</div><div>S (BS): TZVP-MOLOPT-GTH-q6</div><div><br /></div><div>Mo (PP): GTH-PBE-q14</div><div>Mo (BS): DZVP-MOLOPT-SR-GTH </div><div>S (PP): GTH-PBE-q6 </div><div>S (BS): DZVP-MOLOPT-GTH</div><div><br /></div><div>I am adding RESP charge printed sections for both the cases in two separate files too.</div><div><br /></div><div>Thanks in advance...</div><div>Prateek.</div>
