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 a 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 pitroget. octahedra distortedin different degrees,.-,,The distortions possess.a trigonal nature.

However, the splitting of the 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 comparison of the e.p.r. spectrum of I with the spectrum of the a,a-diphenyl-P-picryl hydr,--.2,.yl radical (DPPH) showed that the, additional hyperfine structure is due Eiolely to the protons of the a-pheriyl groups.
