Paper Abstract

Variable-temperature Raman studies were carried out for some representatives of a novel class of industrially promising (sigma) -conjugated polymers-polymetallanes of the type (R2M)n, M equals Si, Ge, Sn. Electronic-conformational nature of the thermochromic phase transitions of order- disorder type exhibited by some of these polymers was investigated. The applicability of Shorygin's semi-classical approach to the pre-resonant Raman intensity enhancement was confirmed experimentally by the example of polysilanes.
