Ai. Aleksandrov et al., INVESTIGATION OF RADICAL PAIRS PRODUCED UPON PULSE ACTION OF ELASTIC-WAVES ON THE YLCATECHOL-3,6-DI-TERT-BUTYL-O-BENZOQUINONE-SULFUR SYSTEM, Russian chemical bulletin, 45(4), 1996, pp. 819-823
The pulse action of elastic waves on polycrystalline mixtures of 3,6-d
i-tert-butylcatechol and 3,6-di-tert-butyl-o-benzoquinone produces rad
ical pairs stable at room temperature, and the addition of polycrystal
line sulfur considerably increases their yield. The dependences of for
mation and decay rates of paramagnetic centers bn the composition of t
he mixture were studied. The threshold character of formation of param
agnetic centers at various powers of elastic wave pulse was establishe
