It is demonstrated that in fullerene C₇₀$C_{70}$, there is a withdrawal of an Electrodynamical forbiddance of a strong quadrupole light-molecule interaction, which is realized in the fullerene C₆₀$C_{60}$. This situation occurs because of the reduction of symmetry of C₇₀$C_{70}$ from the icosahedral symmetry group Y_h$Y_h$ to the group D_5h$D_{5h}$. The withdrawal results in appearance of the lines in the SERS spectra of C₇₀$C_{70}$, which are forbidden in usual Raman scattering and are allowed in infrared absorption. The measured SERS spectra of C₇₀$C_{70}$ demonstrates existence of such lines that strongly confirms our ideas about the dipole –quadrupole SERS mechanism.

证明在富勒烯C _70中$C_{70}$，在富勒烯C _60中实现了强大的四极光分子相互作用的电动力学禁忌$C_{60}$。发生这种情况是由于C ₇₀的对称性降低$C_{70}$来自二十面体对称群Y _h${ÿ}_H$到小组D _5h$d_{5H}$。撤离导致在C ₇₀的SERS光谱中出现线条$C_{70}$，这在通常的拉曼散射中是被禁止的，并且在红外吸收中是允许的。C ₇₀的实测SERS光谱$C_{70}$ 证明了这些线的存在，有力地证实了我们关于偶极-四极SERS机制的观点。
