Upon reduction of polycrystalline MoO3 with atomic hydrogen at room temperature well resolved ESR spectra were obtained showing the presence of Mo5+ ions in a crystal field of nonaxial symmetry.The spectra are characterized by gx = 1.944, gy = 1.955, gz = 1.879 and ax = 3.2 mT, ay = 3.0 mT, az = 7.0 mT.The hydrogen treatment also resulted in the formation of hydroxyl groups as evidenced by IR absorption measurements.The reduction of the MoO3 samples was markedly enhanced by illumination with wavelengths /= 330 nm. . - keyword: ESR of MoO3 / Semiconductor / Reduction and Photoreduction
