Sažetak
Two-dimensional hyperfine sublevel correlation (2D-HYSCORE) spectra of the γ -irradiated crystal of L-alanine were employed to detect possible contribution of 14N hyperfine splitting to the spectrum of stable radical centers at room temperature. The 14N hyperfine and quadrupole tensors are evaluated and they are assigned to abstracted NH3 molecule, which appeared as a product of the first stable radical formation. The obtained results have been discussed as potential new elements for description of the environment of the first stable L-alanine radical in the crystal lattice.
