WebWhat is the abbreviation for Solvent-Separated Ion Pairs? What does SSIPS stand for? SSIPS abbreviation stands for Solvent-Separated Ion Pairs. Weboxocarbenium ions will be separated from their counterions by solvent molecules (sol-vent-separated ion pairs, SSIPs), and there will be no influence of the counterion on the selectivity of the reaction. Moving toward the S N2 side of the spectrum contact (or close) ion pairs (CIPs) are encountered, and in reactions of these species, the counterion

WebTwo types of ion pairs have been recognized, namely, contact ion pairs in which the cation and anion are in physical contact, and solvent-separated ion pairs in which one or two solvent molecules are situated between the cation and anion. Ion pairing must be considered in developing a complete picture of an electrolyte solution. WebOct 10, 2006 · Two different types of ion pairs between AOT and CV, i.e., contact ion pair (CIPs) and solvent-separated ion pair (SSIPs), were characterized by UV-vis spectroscopy …
