The dielectric relaxation peak of pure water is one of the most measured and studied phenomena in Dielectric Physics.  The debate rages as to whether it’s almost Debye like character is the result of the reorientation of an apparent dipole moment of the water cluster, or simply the cumulative effect of single water molecule reorientation.  Furthermore, like many glass formers, it has a high frequency excess wing and a boson peak.  However, If we accept the first origin (water cluster reorientation), then it is still an open question as to what causes the reorientation of the apparent dipole.  Usually the excess wing is treated as evidence of a further dielectric process, existing the THz region of the spectrum.  In this talk we present evidence that the microscopic origin of both the excess wing and the main relaxation peak of pure water is the same.  The origin of these two features is explored and the implications for the fundamental relaxation of water are discussed.
