Graph 1: 1 / Voltage vs. Frequency (cycles per second)

Notice in Graph 1 that as the applied current goes from low to high frequency the voltage measured goes from low to high (in this graph the voltage is depicted as 1/voltage, so it appears to go from higher to lower, but that is not the case). This cha nge in voltage can be used to estimate the dipole moment on the nanocrystals, but is somewhat cruder than the other method (see Graph 2).
