氢化非晶碳中聚乙炔和聚对苯乙炔链的共振拉曼散射
Resonant Raman scattering from polyacetylene and poly(p-phenylene vinylene) chains included into hydrogenated amorphous carbon
摘要：
在N-IR - UV范围内，非晶氢化碳（a-C：H）的共振拉曼散射揭示了反式聚乙炔（反式-（CH）x）链的内含物，其近似长度高达120个C=C单元和聚（对苯撑亚乙烯基）（PPV）聚合物链的内含物。PPV是由一个强大的色散模式，在约。1175 cm-1。研究发现，掺入a-C：H的Ag的trans-（CH）x模对不同激发能的拉曼响应与独立链的拉曼响应一致，从而有利于复杂碳质材料光谱中trans-（CH）x的识别。
英文摘要：
The resonant Raman scattering in N-IR - UV range from amorphous hydrogenated carbon (a-C:H) reveal inclusions of trans-polyacetylene (trans-(CH)x) chains with approximate length of up to 120 C=C units and inclusions of poly(p-phenylene vinylene) (PPV) polymer chains. The PPV is evidenced by a strong dispersive mode at ca. 1175 cm-1. It was found that the Raman response from core Ag trans-(CH)x modes incorporated into a-C:H to changing excitation energy is identical to of free-standing chains thus facilitating identification of trans-(CH)x in complex carbonaceous materials spectra.
