Coil to globule transition in poly(N-isopropylacrylamide) aqueous solutions was studied using spin probe continuous-wave electronic paramagnetic resonance (CW EPR) spectroscopy with an amphiphilic TEMPO radical as a guest molecule. Using Cu(II) ions as the “quencher” for fast-moving radicals in the liquid phase allowed obtaining the individual spectra of TEMPO radicals in polymer globule and observing inhomogeneities in solutions before globule collapsing. EPR spectra simulations confirm the formation of molten globules at the first step with further collapsing and water molecules coming out of the globule, making it denser.

Current paper systematizes the work devoted to the application of the aromatic spin probe EPR spectroscopy for the study of heterogeneous alumina catalysts, as well as supplemented by new researches carried out in IHP SB RAS. The advances of the method and the mechanism of probe molecules interaction with active surface sites and their nature are considered. There are noted some contradictions in views on mechanisms, nevertheless the modern point of view tends to participate BAS in the ionization of aromatic probe molecules.
