(a) Schematic for point group m (C1h). (b) and (c) Transformation of the dipole moment in point group m (C1h) viewed along different crystallographic directions. (d) Schematic for point group 2 (C2). (e) and (f) Transformation of the dipole moment in point group 2 (C2) viewed along different crystallographic directions. In (a)–(f), a ≠ b ≠ c, α = γ = 90°, β ≠ 90°. |
