Vector coupling diagram

Draw vector coupling diagrams to show all possible ways in which vectors L = 3 and S = 5/2 can couple. 

From the relation A3 = a3 we can relate the measured value for A3 to the "uncoupled" value a3, which is 33 = -20 MHz for a ferric FeS4 site (11). From the vector coupling diagram we obtain... 

Figure 5. Vector coupling diagram for the three sites of the FesSa cluster of Fd II. S = 2 is the system spin and S3 = 5/2 is the spin of the Fe3+ site. S12 is the spin of the delocalized dimer, z is the direction for which is evaluated.
