“…The peaks in p(E) on either side derive from the p-resonances which are split into two groups by interactions between the sites in a cluster. Whilst equation (1) true density of states, the similarity of the two curves for the staggered and eclipsed local configurations suggests that the energy gap for a tetrahedral glass should be very similar to the energy gap in the corresponding crystal-in full agreement with experiment (Stuke 1970).…”

“…Stuke [19] has suggested that amorphous Te has a disordered chain structure in which the inter-chain bonding is weaker than that of trigonal Te, but in which the intra-chain bonding is stronger and more nearly purely covalent. X-ray studies of amorphous Te are clearly needed to substantiate this picture.…”

The frequencies of the long wave optical phonons in trigonal Se and Te are compared.Differences in the relative frequencies of the A, and A, modes, and in several of the elastic constants as well, are attributed to differences in the intra-and inter-chain bonding. These comparisons are made quantitative by defining reduced lattice dynamical properties in which the nearest and second nearest neighbor distances are used as scaling parameters respectively for the intra-and inter-chain properties. The comparison is extended to the optic mode frequencies of amorphous Se and Te.Die Frequenzen der langwelligen optischen Phononen in trigonalem Se und Te werden verglichen. Die Unterschiede in den relativen Frequenzen der A,-und A,-Moden und einiger elastischer Konstanten werden Unterschieden in den Bindungen innerhalb der Kette (Intra-Bindung) und den benachbarten Ketten (Inter-Bindung) zugeschrieben. Die Vergleiche werden quantitativ ausgewertet, indem die reduzierten, dynamischen Eigenschaften des Gitters definiert werden. Der Abstand nachster Nachbarn definiert die Intra-Bindungen und der niichste Abstand zwischen Atomen benachbarter Ketten definiert die InterBindungseigenschaften. Der Vergleich wird auch auf die optischen Freqnenzen von amorphem Se und Te ansgedehnt.

Atomic structures of Se clusters impregnated into ZSM-5 single crystals have been investigated through structural and optical experiments. Raman-scattering spectroscopy suggests that Se in the zeolite takes single chain structures. X-ray diffraction implies that the chains form fourfold ͑not threefold as in trigonal Se͒ helices. The chain length is estimated from weight and electron-spin resonance measurements at 10 2 atoms. The material shows an optical absorption edge at ប Ӎ 2.2 eV, which accompanies dichroism, suggesting chain alignment in the zeolite pores.
