... this uncertainly, a suite of studies by the NMR method was conducted, it consisted in comparing spectra of transverse relaxation T2 with different fluid saturation: water or kerosene. In case of real hydrophilicity, the spectrum of the water-saturated sample must be located in an area of lesser relaxation times...
