Admittedly, to our surprise, this approach worked, and we could get clear continuous wave (CW) EPR signals using a wide range of anionic organic bases, in different solvents at room temperature, in fluid solution (Figure ). For a bare [1 •-], one would expect a g-value slightly larger than 2.0023 because the unpaired electron is promoted to a previously unoccupied orbital in the nitro group. The electron spin then interacts with the nuclear spin of 14 N (I=1), resulting in a 1:1:1 triplet, which is further split by the nuclear spins (I=1/2) of one para and two set of equivalent meta and ortho hydrogen atoms, leading to a theoretical maximum number of 54 transitions. Then, the presence of alkali metals [1 •-][X + ] (X=Li, Na, K) with nuclear spins I=3/2 catapults these to a possible 216 peaks. Depending on the relative strength of the hyperfine coupling constants A (Equation ) and spectral resolution, these might overlap, simplifying the spectrum. Our results exemplify this, with spectra spanning from a single unresolved isotropic transition to extremely fine-structured signals with +190 peaks (Figure ).
