Temperature Dependent ESR Studies on Platinum Pyrimidine “Blues”: Evidence for a Structural Instability ?

Abstract: Frozen samples of aqueous solutions of oxidized Pt 6-methyl-uracil “blue” were studied by ESR spectroscopy at temperatures T ranging between - 196 °C and - 10 °C. When T was raised a distinct change in the line pattern was observed at about -35 °C. The resulting type of spectrum is very similar to the ESR spectrum of MAGNUS’ Green Salt. The observed effect is suggested to be due to a change of the nature of the system’s electronic states possibly indicating a structural rearrangement
