• New absorption band have been observed in KCl-KI(10 mol%) crystals X-rayed near liquid helium temperature and attributed tentatively to complex H(ICl_3^<3->) centers. The main absorption band is located at 425nm and a sub-band at 800nm with the half width of 0.43eV and 0.21eV, respectively. The dichroic property of the bands is consistent with that of a center with its internuclear axis along <110> directions. The center is thermally reoriented above about 70K with E_<reori>=0.10±0.01eV and destructed above 190K with E_<dest>=0.16±0.01eV. The peak positions, the half width, the polarization, the oscillator strength and the thermal properties of the bands are qualitatively discussed by a model of the heteronuclear diatomic molecule. The qualitative analysis suggests that the hole of the complex H center is found having a large probability around the I atom as one of constituents.
