Ground signal from our apparatus is always below 30-50 photons per sec. The cited reactions give a photon output of even dozens of thousands of photons
I'm referring to individual reactions only. The "simplest" example is dropping water onto solid NaOH. Which excited intermediates relaxe with photon emission in our spectral window? (our photomultiplier tube has a 330-550nm spectral sensitivity).
Note: when potassium hydroxide or barium...
yes. water-NaOH, water-TritonX100, formaldehyde-NaOH are some examples. Light was produced in all the above reactions, though with different intensities (photons per sec)
Roughly, emitted light is in the green-blue region, as assessed by a photomultiplier tube close to the reaction vessel with (broad band) thin plastic filters in between
dear all,
in a series of experiments on the interaction between sodium hydroxide and other molecules such as water, Triton X-100, formaldehyde and others, we found emission of light. Besides the formaldehyde-NaOH interaction, i.e. the Cannizzaro reaction in which some intermediates may form...
