I have done electrochemical impedance by using cyclic voltammetry for one organic material. from that, I plotted bode diagram. but actually, I am very confused about how to find the capacitive response frequency from the plot of Phase angle Vs log frequency? please suggest me..
Dear Giddaerappa-Kuntoji,
you might find helpful some initial refs[1-4], as a starting point for your further studies.

From body plot you can select capacitance versus frequency or real and imaginary component of the impedance. It depend on the device you used for EIS analysis.
