The “Techalet” molecule absorbs light at 613 nanometers, according to the research of J Wouters and A Verhecken this is also the number of the mitzvot (commandments) in the Torah”
From the Research Paper :
Visible absorption maxima in the blue
region is a maximum from 613 nm (in I) to 606 nm (in III) to 600 nm (in IV) is also
evident. By means of the diode-array detection facility, not
only could the detection wavelength be chosen to give an
optimal response for each product, but also each peak in
an unknown sample could be fully characterized by its
u.v. and visible light absorption spectrum, taken on-line
