127I NQR and spectroscopic investigation of impurity-doped and mixed lithium iodate Li1−xHxIO3 crystals

The 127 I NQR, IR absorption and Raman spectra of impurity-doped and mixed lithium iodate Li 1− x H x IO 3 crystals grown from water solutions with different LiIO 3 /HIO 3 ratios were investigated depending on the content of the impurity hydrogen x . The NQR results suggested that, at small concentration of doping iodic acid x x 1− x H x IO 3 are formed.
