  Thank you kindly for the lead. I am glad to hear porphyrin chemists actually exist !... Just joking, please don't take it offensively.

  What are set of rules I would use to figure out if bilverdin-IX alpha is an 15Ea,15Es,15Zs or 15Za isomer, likewise for C4=C5 & C10=C11 ethenes? I have done extensive research on web on this problem and read countless articles, where everybody loves to use that terminoloy in their publications, but no one can explain how. Are there any porphyrin organic chemists out there?

  Of cours you can capture the phase from "special" anomalous (heavy atom) diffraction differences.

  It is really Euler's formula (complex exponential function) that is the beauty of why FT "works so to say", because now you can treat any sinusoidal wave as "these sines and cosines". Referring to the nice spinning top analogy by Andrew, now you can capture the red dot as the "cosine part as frequency and amplitude. In X-ray diffraction, you can't capture the phase (sine part) . I'd like to add that a crystal is not really sinusoidal (it doesn't vary over time), although it is periodic in the "repetitive meaning sense". Thus the sinusoidal pattern (Time domain) in the diffraction pattern spots comes from the x-rays ,which as an electromagnetic wave is sinusoidal, in combination with the periodic "repetitive" unit cells of the crystal.
