✦ Synopsis

viscosity the ESR spectrum of ( I ) shows a poorly resolved hyperfine structure (six lines), which we ascribe to a diradical whose exchange energy J is Large compared with the N coupling constant uN["' ( J $ u N ; 4 2 = 5.5 & 1 G); in addition there is the interaction energy of the electrons with the ortho-proton (aHO= 3.

In ethanol glass, ( I ) shows the characteristic spectrum of a non-cylindrically symmetrical triplet. The half-field resonance shows the (Am=2) transition. In the (Am=l) spectrum (Fig. 1) there are three pairs of bands from whose uN= 10.8, ~,o,n=3.1, ~,m=0.95 G. 9YY Y II H , c 2 . 20 qzz z ll H, c f 0 + 3 E gxx
