Abstract
The intramolecular dynamics of a silicon biradical complex with o-semi quinone ligands was studied in a frozen toluene solution. Analysis of the broadening and shifts of the canonical components in the ESR spect rum of this biradical allows one to detect the abrupt reorientation of the magnetic axes due to intramolecular single bond-unpaired electron exchange. The frequencies of chemical exchange at low temperatures we re estimated.
