However the C-symmetry of the ligand is also important in controlling this enatioselectivity.

In physics, C-symmetry means the symmetry of physical laws under a charge-conjugation transformation.

The molecule has idealized C-symmetry, like hydrogen peroxide and related molecules.

This property is what is meant by the "maximal violation" of C-symmetry in the weak interaction.

C-symmetry and CP-symmetry violation.

(Some postulated extensions of the Standard Model, like left-right models, restore this C-symmetry.)

Efforts during the late 1950s revealed the violation of P-symmetry by phenomena that involve the weak force, and there were well-known violations of C-symmetry as well.

Electromagnetism, gravity and the strong interaction all obey C-symmetry, but weak interactions violate C-symmetry.

It was believed for some time that C-symmetry could be combined with the parity-inversion transformation (see P-symmetry) to preserve a combined CP-symmetry.

Treatment of TiCl with acetylacetone gives cis-TiCl(acac), a red-coloured, octahedral complex with C-symmetry:

These require that baryon number is not conserved, that C-symmetry and CP-symmetry are violated and that the Universe depart from thermodynamic equilibrium.

One set comes from the Poincaré symmetry-J, where J, P and C stand for the total angular momentum, P-symmetry, and C-symmetry respectively.

If weak interactions are present, reversible dynamics are still possible, but only if the operator π also reverses the signs of all the charges, and the parity of the spatial co-ordinates (C-symmetry and P-symmetry).
