Abstract

The structure of the oxygen atoms lattice in hexagonal ice corresponds to symmetry group D<Stack><Subscript>6h</Subscript><Superscript>4</Superscript></Stack> with four atoms A1, A2, A3, A4 in the unit cell (Fig. 1). The symmetry types of the principal normal modes of such a lattice are A1g, B1g, B2u, E- g, E+ g, and E+ u. The active modes in the first-order Raman effect are A1g, E- g and E+ g.
