<div>Dear all,</div><div>I have calculated Restrained Electrostatic Potential (<span>RESP</span>) charges for my metal-water complexes (using the input file given in the cp2k tutorial given for methanol) and I have found that in the output file there are RESP charges on the atoms along with Mulliken and Hirshfeld charges. It is observed that these three sets of <br></div><div>charges are completely different from each other. <br></div><div>Mulliken charges being more sensible (in terms of chemical knowledge or electronegativity). Hirshfeld is completely off and RESP is also not so convincing.</div><div><br></div><div>For example, oxygen of water coordinated to the metal ion is found to be positive and hydrogens are negative.</div><div><br></div><div>Can anybody comment on the same or any literature which will help me to understand it.</div><div><br></div><div>Which one is the more accurate?</div><div><br></div><div>Any help is appreciated.</div><div><br></div><div>Regards</div><div>N Choudhury<br></div>
<p></p>
