摘要：
The effects of inert (non-hydrogen donor) cosolvents on transient complex formation between a nitroxide radical and two hydrogen donors are examined by EPR methods. For both C6H5OH and CF3CH2OH the complex association constants are lower and the radical-donor hyperfine coupling constants are higher in more polar cosolvents. The results are interpreted by using a model based on donor acidity and the role of the cosolvent in solvating each of the species in solution. © 1991.
