富勒烯C_（70）的几个重要的物理化学性质已被确定。荧光很弱，但可测量。三重态C70和单线态氧的产率很高，但不是很定量;三重态能量略高于33 kcal/mol。三重态的吸收光谱在某些方面类似于C60的吸收光谱，但稍强，并且缺乏C60光谱中存在的强红红外吸收。总体而言，C70的行为与C60相似，但较低的对称性放松了某些吸收和发射过程的禁止性。
Several important photophysical properties of the fullerene C70 have been determined. Fluorescence is weak but measurable. The yields of triplet C70 and of singlet oxygen are high, but not quite quantitative; the triplet energy is slightly above 33 kcal/mol. The triplet has an absorption spectrum that resembles that of C60 in some respects but is somewhat stronger and lacks a strong red-infrared absorption present in the C60 spectrum. Overall, the behavior Of C70 is similar to that of C60, but the lower symmetry relaxes the forbiddenness of some absorption and emission processes.
