The interaction includes excitation of at least one ESR transition in the sample. The sample is also illuminated by the two THz pulses together, with an inter-pulse delay ?, generating a third signal BAB. A nonlinear signal BNL is then derived via BNL=BAB?BA?BB. This nonlinear signal BNL can be then processed (e.g., Fourier transform) to study the properties of the sample.
