for qualitative determination of statistical characteristics

TEXT.. The paramagnetic,electron resonance.in silicate, phosphate, and
j borate g7iasses, to which were added-K 0,11a 0, and Li 0 one after
2 2
other, was investigated for 9330 and 458 Me/see at temperatures of
n

300 and 770K. All samples contained 1 to 5 mole% Ti:O To obtain
2-
3+
Ti ion3 in the glasses, the latter were boiled with a smoking flame
under strongly reducing conditions. To each charge were added carbonates
of.alkali -;,-.,0,als.and carbon in quantities of about 0-5% by wcight.
Conclusionss~ The borate glasses contained no trivalent Ti ions. -In
the silicate and phosphate glasses, the T13+ ions "are surrounded by

orbital triplet in the phosphate glasses is larger than in the silicate
glasses. In the iilicate glasses, the splitting i3 largest when the
Li ions are replaced by Na ions, and the Na ions by K ions. A

due Eiolely to the protons of the a-pheriyl groups. It may be explained by

ty of related free radicals from the eop*ro spectra are estimated
by tho raethod of J. A. Weils.K. V. Banep Jo M* Kinkade (J. Phys. Chem.,
65, 7-40 (1961)) showed that-I is chemically more stable than DPPH. Its
stabi-Uty may be due to steric factors reducing the possibility of chemical
reactioas with other substances. The values obtained from the e.p.r.
spect.-ra of I in finely crystalline state, which may contain solvent, were
15.7 + 0.3 oersteds for 6H at 2950K, 10-5 + 0-3 oersteds a 77 0F., 1 .43
