“…As for the dynamic range of the evaluated spectral signals, in all three types of spectral measurements (diapasons), it did not exceed the available dynamic range of receiving tracts of spectrometers. Thus, spectral measurements were carried out at sufficient levels of signal/noise ratio, which excluded the influence of background noise of equipment on the obtained results [12].On the other hand, it is not surprising that the identified portions of spectra, characterized by the most prominent difference in homeopathic-like preparations and hidden/apparent control, lie in the areas of maximal water absorption (in neighborhood of minima of transmission and refractive indexes), because in these regions, intensive interaction of emission of spectrometers with a molecular structure of water may be expected [12].…”
