 The subscript indicates the moment such that formula_46 contributes a derivative-shaped signal and formula_47 and formula_48 contribute regular absorptions.Additionally, a zero-field absorption term formula_52 is defined.The relationships between formula_29, formula_54, and these Faraday terms are 
for external field strength formula_44, Boltzmann constant formula_58, temperature formula_59, and a proportionality constant formula_60.
