The recently discovered novel giant polar magneto-optical Kerr rotation of 90{degree} in CeSb is compared to previous record Kerr signals of the order of 10{degree}, and to another newly discovered giant Kerr signal of 22{degree} in CeS. An analysis of the temperature and field dependence of the off-diagonal conductivity spectra of CeSb is presented which allows an empirical assignment of several structures to electronic transitions. In particular, a folding of bands due to magnetic superstructures in a ferrimagnetic phase is shown to account for three additional peaks. {copyright} {ital 1997 American Institute of Physics.}
