Broadband spectra of ordinary water, heavy water, and ice are analyzed in terms of the dynamic conductivity. It is shown that the spectrum below 1015Hz satisfies the sum rule for the oscillator strength and is related to the dynamics of the proton/deuteron subsystem in the quasilattice of low-mobility oxygen atoms. Debye relaxation andOHband are represented as a result of the same mechanism, i.e., the proton motion in the harmonic potential averaged over different observation periods.
