The EPR and optical absorption spectra of paramagnetic centers produced by X‐irradiation in LiNaSO 4 single crystals were investigated. 7 EPR lines are observed at room temperature and 6 more lines – at LNT. The angular dependences of line positions at LNT are studied and the principal g ‐factor values are defined. The comparison with published data permitted to assign six the most anisotropic lines to ion‐radical SO 4 −with different orientations in the lattice; two lines to ion‐radical SO 2 − ; slightly anisotropic doublet line – to O 3 −ozonide ion; isotropic line with g = 2. 0045 – to ion radical SO 3 − .
