“…The proton and deuteron spin-lattice relaxation times, T 1 , have been reported in the literature for H 2 O [29,30] and D 2 O, [31,32] both at temperatures down to À15 8C. As is shown in Figure 5, the values of T 1 extrapolate to zero at t 0 = À33 8C for H 2 O and t 0 = À22 8C for D 2 O, that is, with the same isotope effect as that found before.…”

“…[2,3] In the literature, several mathematical descriptions of the T 1 versus temperature relationship have been examined, in view of the non-Arrhenius character. [29,30] However, none of these treatments report or predict a zero value at some temperature in the supercooled region.…”

“…The scaling is indeed excellent, which is also the case in the plot of T 1 in conjunction with the self-diffusion coefficient, [21] shown in Fig . Proton [29,30] and deuteron [31,32] spin-lattice relaxation times as a function of temperature. Curves: graphical extrapolation drawn by eye.…”

An earlier study on the properties of supercooled water and some solutes obtained by simple graphical extrapolation of data available in the literature, determined above the freezing point, led to the hypothesis that water could have a temperature of structural arrest at t0 =-30 °C for H2 O and -22 °C for D2 O. From the present investigation of many more properties of a widely varied nature, this discovery is confirmed throughout. The method is compared with the classical logarithmic Arrhenius and van't Hoff methods that predict t0 always to occur at 0 K, and with the more recently used power law dependence method. With the latter, extrapolated plots intersect the temperature axis at or near to a value of ts =-45 °C, that is, systematically more negative than t0 . It is argued that this ts value, which is the so-called singularity temperature, is likely to be an artefact. It is suggested that, instead of using modified van 't Hoff or Arrhenius relationships to describe temperature dependences in the full temperature range, polynomials in (t-t0 ) should be used.

“…However, it is worth noting the strong temperature correlation of the dielectric time relaxation, t D , with viscosity, Z (t D T/Z = const), 62 and proton spin-lattice relaxation time, T 1 (T 1 t D = const). 63,64 Furthermore, the dielectric relaxation practically does not react upon changes in pH. [65][66][67][68] Based on these experimental findings, the orientation defects in some papers 50,60,[69][70][71] are considered to be the dominant mechanism in the dielectric relaxation.…”

Although relating to the same system, the interpretations of the water spectra from Raman and Dielectric spectroscopy present independent pictures of the nature of water. We show that in the overlap region of the two methods it is possible to combine these views into a coherent concept of what drives the dynamic features of water. In this work, we develop the idea that the dielectric relaxation in water is driven by the migration of defects through the H-bond network, leading to a Debye-like peak in the lower frequencies. The deviation from the Debye law in the higher sub-THz frequencies is traced to a global fluctuation of the same H-bond network, clearly evident in the Raman Spectra. By incorporating these two views, a mathematical formalism is presented that can aptly explicate the dielectric spectra of liquid water.
