Molecular symmetry - Wikipedia
Plane of symmetry: a plane of reflection through which an identical copy of the original molecule is generated. This is also called a mirror plane and abbreviated σ (sigma = Greek "s", from the German 'Spiegel' meaning mirror). [6] Water has two of them: one in the plane of the molecule itself and one perpendicular to it.
12.2: The Symmetry of Molecules - Chemistry LibreTexts
2020年1月13日 · Reflection in the plane leaves the molecule looking the same. In a molecule that also has an axis of symmetry, a mirror plane that includes the axis is called a vertical mirror plane and is labeled \(\sigma_v\), while one perpendicular to the axis is called a horizontal mirror plane and is labeled \(\sigma_h\).
In a molecule that has a symmetry axis, a mirror plane that includes the axis is called a vertical mirror plane and is labelled σ v , while one perpendicular to the axis is
Rotary-Inversion Symmetry: Mirror Planes - University College …
The operation of mirror symmetry is equivalent to a rotation of 180° about an axis perpendicular to the mirror plane followed by inversion at the point where axis and plane intersect. The notation for this operation is "-2", i.e. a mirror plane is simply the …
Reflecting on symmetry | Maths | RSC Education
Reflection symmetry elements (usually described as planes in 3D) are denoted by the Greek letter s (sigma). This is often accompanied by a subscript to specify more precisely, for example s v and s h denote vertical and horizontal mirror planes.
R/S optical isomerism explained asymmetric chiral isomers …
Not quite as symmetrical as CH 4, but there is a plane of symmetry originating from the planar arrangement of the F-C-F bond with respect to the two hydrogens (or H-C-H with respect to the 2 fluorine atoms). Therefore the mirror images can be super-imposed on each other - the mirror images are identical.
10.1.3: Mirror Planes - Geosciences LibreTexts
In shorthand notation, we use the letter m to designate a mirror of symmetry. Reflection is the symmetry operation, and the mirror plane is the symmetry operator. Reflection often relates identical faces on a crystal. Figure 10.8 a shows a butterfly that has the same symmetry as a lion.
