TLDR
Using double nuclear resonance with spin mixing by level crossing (DRLC) and by continuous coupling (DRCC), the nuclear quadrupole resonance of 17O and 2D has been measured as a function of isotopic enrichment in the high-pressure ice forms Ice V, Ice VI, Ice VIII, and Ice IX as mentioned in this paper.About:

Experimental and theoretical determination of the temperature dependence of deuteron and oxygen quadrupole coupling constants of liquid water
TL;DR: In this article, the authors determined the quadrupole coupling constants for the deuteron and the oxygen nuclei in neat, liquid water by both theoretical and experimental methods, and reported the theoretical values of χD=264 kHz and χO=8.4 MHz.

Determination of the Rotational Correlation Time of Water by Proton NMR Relaxation in H217O and Some Related Results
TL;DR: In this paper, the 1H-17O dipolar contribution to the proton longitudinal relaxation rate in 17O-enriched water yields a correlation time for reorientation of the O-H vector τrOH = (1.71 ± 0.07) ps in H2O at 25 °C.

On a nearly proton‐ordered structure for ice IX
TL;DR: In this paper, single-crystal neutron diffraction was used to show that ice IX, the low-temperature modification of ice III, has almost completely proton-ordered structure in which the ordered component contains two types of water molecules, type 1 in a site of no point symmetry, and type 2 on a twofold axis, each forming four hydrogen bonds in a threedimensional framework.

Infrared Spectra of Ices II, III, and V in the Range 4000 to 350 cm—1
J. E. Bertie,E. Whalley +1 more
TL;DR: The infrared spectra of Ices II, III, and V between 4000 and 350 cm-1 have been obtained in this paper, where the mulls were made at appropriate pressures and temperatures, cooled under pressure to liquid-nitrogen temperature, and removed from the pressure vessel.
