Question:

Figure 4.43 shows the 9.214GHz EPR spectrum arising from the two sites of Co2+ (59Co, 100% abundant, I = 7/2) doped into magnesium acetate. The sites differ slightly in their effective hyperfine coupling constants, and more significantly in their g-values. 

(a) Calculate the g-values for the two sites.

(b) Explain why the central peak is more intense than the peaks appearing at higher magnetic field. 

(c) What would happen if the differences in g-values of the two sites is smaller than is observed in Fig. 4.43?
