On observation of so-called “water rhythms” by absorption spectroscopy methods

Experiments on observation of quasiperiodic fluctuations in optical absorption of liquid water (socalled “water rhythms”) were reproduced by IR Fourier spectroscopy methods. Slow in time changes in the optical absorption spectra were observed using different Fourier spectrometers with different metrological characteristics. These changes were within the region of experimental accuracy determined by a slow drift in parameters of the measurement equipment. No “water rhythms” were found in our experiments.
