IR Raman and Hyper-Raman Modes

Symmetry Adapted Modes
The program calculates the symmetry adapted modes for Γ point and classifies them in IR, Raman and Hyper-Raman active modes.

There are two different ways to introduce the input of the program:
  • OPTION A: Space group

    • Space group number.
    • The Wyckoff positions for the atoms in a structure (one have to select this in the next form).

  • OPTION B: Structure

    • The structure in BCS format or in CIF file.
Only the default choice for the conventional setting of the space groups is used.

If you are using this program in the preparation of a paper, please cite it in the following form:

Kroumova et. al. Phase Transitions (2003), 76, Nos. 1-2, 155-170.
