 abstract = {Molecular dynamics simulations of the orientational dynamics of water
molecules confined in narrow carbon nanotubes and nanorings reveal that
confinement leads to strong anisotropy in the orientational relaxation.
The relaxation of the aligned dipole moments, occurring on a time scale
of nanoseconds, is 3 orders of magnitude slower than that of bulk water.
In contrast, the relaxation of the vector joining the two hydrogens is
ten times faster compared to bulk, with a time scale of about 150 fs.
The slow dipolar relaxation is mediated by the hopping of orientational
defects, which are nucleated by the water molecules outside the tube,
across the linear water chain.},
