Abstract

A rate constant is deduced for the reaction of tert-butoxy radicals and trimethylsilane from the measurement of the phase shift between the modulated light source and the ESR signal of trimethylsilyl radical. The rate constant was found to $3{\times}10^{-2}M^{-1}{\cdot}sec^{-1}$ at $-50^{\circ}C$.

Modulated light signal과 trimethylsilyl 유리기의 전자상자성 공명 signal과의 phase shift를 측정함으로써 t-butoxy 유리기와 trimethylsilane의 절대 반응속도 상수는 $-50^{\circ}C$에서 $3{\times}10^{-2}M^{-1}{\cdot}sec^{-1}$으로 얻을 수 있었다.
