Effects of adsorbed hydrogen on ESR at g =1.961 appeared from ZnO of a powdered form were studied in company with NMR measurements of protons for adsorbed hydrogen and hydroxyl groups remaining on the surface. The existence of an accumulation layer on the surface of ZnO was confirmed. The ESR at g = 1.961 was concluded to be originated from degenerated conduction electrons in the accumulation layer. Chemisorbed hydrogen decreases the relaxation of spins of the conduction electrons at the surface. Observed NMR spectra reveal that a part of chemisorbed hydrogen is in a state similar to hydroxyls and the other is in a state with free motions on the surface. A molecular form hydrogen adsorbed with hydroxyls on the surface is found, which is assumed to be H3+or O-H3+ and adsorbed with an ionic potential of ZnO. Its NMR line shifts by about 15 ppm from the position of protons in water to low field direction.
