Sulla determinazione della struttura, proprietà fisiche ed effetti dinamici delle coppie ioniche, determinati mediante la spettroscopia di risonanza di spin elettronico

The physical, chemical, and thermodynamical properties of the ion pairs formed by alkali cations and organic anion radicals are widely discussed. The most important ion pairs studied in the literature and their classification (tight or loose, dynamical or static) are briefly illustrated. The application of the electron spin resonance spectroscopy (esr) for determining the thermodynamical and kinetical parameters, governing the exchange processes present in the dynamical ion pairs, is rationalized in terms of the most commonly used quantum mechanical theories.
