Spin precession of channelled particles in bent crystals at the LHC gives unique possibility for measurements of constants determining T-odd, P-odd (CP) violating interactions and P-odd, T-even interactions of charm, beauty and strange charged baryons with electrons and nucleus (nucleons), similarly to the possibility of measuring their electric and magnetic moments. For a particle moving in a bent crystal new effects caused by non-elastic processes arise. In addition to the spin rotation around the effective magnetic field direction (the bending axis direction), due to electromagnetic interactions and leading to changes in spin direction in the plane orthogonal to , the spin acquires projection along the direction. Moreover, when spin rotates around the direction of the electric field or the particle momentum , a spin component along or , respectively, is induced.
