摘要：

Magnetic-field effects on the decay kinetics of chain-linked triradicals have been investigated in acetonitrile at 293 K. The decay rate of the triradical linked by an 8-methylene chain was 1 x 10(7) s(-1) under zero field and decreased with increasing field to attain a constant value of 2 x 10(6) s(-1) at 2-10 T. These values were one order larger than those of the corresponding ketyl-diphenylmethyl biradical. (C) 1999 Elsevier Science B.V. All rights reserved.
