It is known that water solutions, which are obtained by electrolysis, manifests fluorescence. Some authors connect this effect to the ROS (Reactive Oxygen Species) both in anode and in cathode compartments. In this article authors in contrast assumed that the fluorescence of the cathode solutions is connected with aqueous hydrogen gas. In experiment, water has got saturated by hydrogen gas. These, definitely containing hydrogen, water solutions are examined. The bubbling of distilled water with hydrogen as well as reaction of water with Mg leads to appearing the wide emission band with the maximum near 410-415nm. The intensity of the fluorescence depends on the quantity of hydrogen gas bubbled through the water, as well as the time of interaction of water with metal magnesium, but she shape and the position of maximum of the fluorescence spectra do not depends on the time of reaction. Also the same band connected with hydrogen is present in water from cathode part of electrolyser. The hydrogen fluorescence in water present at room temperature at excitation band 260 nm.
