摘要: Abstract Polarized Raman and optical absorption spectra of the natural mordenite single crystals containing adsorbed species sulfur, selenium, or tellurium within one-dimensional channels (diameter channel ca. 0.7 nm) have been studied. The bands in spectra, which are polarized along direction, attributed to helical chains. Experimental evidence is shown for assignment other ring-like molecules S 6 , 8 Se probably Te .
