TLDR
In this paper, the position of the ΝN\(\mathop - \limits^ \bullet \)O band in the spectra of cyclic nitroxyl radicals depends on the size of the ring.Abstract:
1.
The use of the Raman spectroscopy method makes it possible to unequivocally determine the position of the band of the stretching vibrations of the
group in the spectra of cyclic nitroxyl radicals.
2.
In the vibrational spectra of five-membered cyclic nitroxyl radicals the band of the stretching vibrations of the
group is found in the 1433–1443 cm−1 region. The position of the ΝN\(\mathop - \limits^ \bullet \)O band in the spectra of cyclic nitroxyl radicals depends on the size of the ring.read more

TL;DR: In this paper , the authors proposed a reaction mechanism to explain the asymmetric behavior of charge transfer reactions by invoking adsorption-desorption processes in organic compounds such as 4-hydroxy-2,2,6, 6,6-tetramethylpiperdinine-1-oxyl (4−hydroxy−TEMPO).
