Application of co-59 NMR to the investigation of interactions between cobalt sepulchrate and various counterions

Research output: Contribution to journal › Article › peer-review

Abstract

Association constants for the ion pairs formed between [Co(Sep)]3+ and the anions fluoride, chloride, bromide, iodide, perchlorate, and oxalate were obtained from the chemical shifts of the Co-59 resonance that occur upon addition of such anions to solutions of the cobalt complex. The usefulness of Co-59 NMR to obtain formation constants, in order to calculate the "true" quantum yields for the ion pairs, is discussed.
