Sodium clusters stability function

Sodium salts of sulfonated triphenylphosphine P(m-C5H4S03Na)3 or alkyltriphenyl-methyltrisulfonates function as stabilizers for hydrosols of colloidal rhodium and (C6H5)2P-p-C6H5S03Na has been used by Schmid to prepare water soluble gold clusters which are isolable and redispersible without agglomeration [202]. 

In the present work, we have earlier looked at the MESP distribution (cf. Section II.3.1) of sodium metal clusters. Generally, a distribution of MESP CPs with large negative function values indicates that a chemical species is highly reactive. On the contrary, a smeared and equivalent natured MESP minima distribution around the cluster is indicative of electron delocalization and stability of the clusters. This delocalization in electrons can be quantified in terms of the standard deviation of the MESP. Table 11.6 reports the total number of MESP minima around the cluster...
