Abstract—Chemiluminescence in solutions during interaction of hydrazine with hypochlorite in the presence
of sensitizers and quenchers is studied. The role of oxygen in this system is shown. It is revealed that the chemi-
luminescent reaction proceeds via the radical oxidation of hydrazine with hypochlorite and formation of triplet
nitrogen, which then reacts with oxygen. The radiation lifetime of an emitter, which is presumably NO with
spin 3/2, is more than 80 ms. The maximum spectral density of radiation is in the violet region of the spectrum.
It is shown that the radiationless transition of excitation energy from the emitter to sensitizers (fluorescein,
rivanol, etc.) or quenchers (phenols) can occur. When sensitizers and quenchers are present together in solution,
they compete for the excited particle.
