Symbol | Property |
---|---|

A | symmetric with respect to rotation around the principal rotational axis (one dimensional representations) |

B | anti-symmetric with respect to rotation around the principal rotational axis (one dimensional representations) |

E | degenerate (German: entartet; two dimensional representations, e.g. in systems with higher order principal axes) |

subscript 1 | symmetric with respect to a vertical mirror plane perpendicular to the principal axis |

subscript 2 | anti-symmetric with respect to a vertical mirror plane perpendicular to the principal axis |

subscript g | symmetric with respect to a center of symmetry (German: "gerade") |

subscript u | anti-symmetric with respect to a center of symmetry (German: "ungerade) |

prime (') | symmetric with respect to a mirror plane horizontal to the principal rotational axis |

double prime ('') | anti-symmetric with respect to a mirror plane horizontal to the principal rotational axis |

The standard convention taxes the Z-axis as the principal axis of the system and the YZ-plane as the principal plane.
