Luminescence data from water, enhanced by laser illumination, collected at 1 sec intervals exhibited patterns of synchronized sinusoidal oscillations of light emission in the blue-green region with a period length of 18.6 min when evaluated by Fast Fourier analysis. The oscillatory patterns recapitulate those attributed previously to alternation of ortho-para nuclear spin pairs of water hydrogens. The resultant light emissions are consistent with the hypothesis that water luminescence is the result of the discharge of energy during the transition between the highest and the lowest energy states attained during the periodic ortho-para nuclear spin pair interconversions. The period length of 18.8 min agrees with the previously found oscillatory period of about 18 min based on FTIR spectroscopic measurements of ortho to para nuclear spin pair alternations also given by changes in redox potential sufficient to drive NADH oxidation.
