We investigate numerically the appearance and evolution of entanglement in spin systems prepared initially in a pure state. We consider the dipolar coupling spin systems of different molecular structures: benzene C6 H6, cyclopentane C5 H10, sodium butyrate CH3 (CH2) 2 CO2 Na, and calcium hydroxyapatite Ca5 (OH) (PO4) 3. Numerical simulations show that the close relationship exists between the intensity of second order (2Q) coherences and concurrences of nearest spins in a cyclopentane molecule.
