Question

(e) Give one example of each of point group D3h and Td.​

Answer 1

Explanation:

order of the D3h point group is 12, and the order of the principal axis (S3) is 6. The group has six irreducible representations. The D3h point group is isomorphic to D3d, C6v and D6. ... The D3h group has eight distinct nontrivial subgroups of seven different kinds: D3, C3h, C3v, C3, C2v, C2, Cs.

The <td> tag defines a standard data cell in an HTML table. ... Data cells - contains data (created with the <td> element)

Answer 2

Answer:

Example of D3h :

1). [3,3,3]+ has three 3-fold gyration points and symmetry order 60. Front-back symmetric groups like [3,3,3] and [3,4,3] can be doubled, shown as double brackets in Coxeter's notation,

2). for example [[3,3,3]] with its order doubled to 240.

Example of Td :

Examples of molecules belonging to the Td point group are P4 (white phosphorus) and methane, CH4. The next Platonic solid with all regular triangles as faces is the octahedron: Here we have six vertices. Through each vertex passes a four-fold axis of symmetry.
