## Abstract The electronic properties of a KNO~3~ crystal near the structural phase transition are investigated by observing ultraviolet absorption spectra. The spectra show an anomalous temperature dependence near the transition point __T__~tr~. The anomalous behaviour of the exponential absorptio
