NQR spectra were observed for α-(CH3)2 TeX2 (X=Cl, Br, I) and (CH3)2 TeI4 at various temperatures. The two 81Br NQR lines were observed above 110 K in α-(CH3)2TeBr2. The characteristic temperature dependence of the 127I NQR line in α-(CH3)2 TeI. can be explained by the 3c—4e bond of the linear I---Te---I group. The positive temperatures dependence of the lowest 127I NQR line in (CH3)2TeI4 is discussed on the basis of the electron population calculated from Townes—Dailey treatment. |
