In this paper the measurement of the ultraviolet absorption edge of LiNbO3 crystal grown from the solid-liquid congruently melt at room temperature is presented. It is affirmed that the absorption edge below 4.0 eV is attributable to indirect transition. The meaning of three straight-lines of the spectral curyo are discussed by studying the α1/2-hv curve of LiNbO3. The energy gap Eg is 3.38 eV.
