摘要：

Polarized Raman spectroscopic experiments have been carried out for the mercuric bromide intercalated Bi2Sr2CaCu2Oy single crystal in order to investigate the evolution bf electronic and geometric structures of host and guest upon HgBr2 intercalation. All the present spectra indicate the presence of the symmetric Linear HgBr2 molecule in the interlayer space of the intercalate together with an interaction between the intercalated HgBr2 and host lattice, which confirms clearly the previous extended x-ray-absorption fine structure/x-ray-absorption near-edge structure results.
