中文摘要:

      用温差光谱法观察系列化合物的紫外吸收温差谱,发现温差谱具有很强的特征性.具有π键的富勒烯C₆₀温差谱峰为负值,负峰的强度随样品温差增大而负荷增大,负峰的峰位无明显移动.

英文摘要:

      UV absorption spectrum measured from difference in sample temperature (SDT) is studied. The change of 10^-3 absorbance can be measured. The UVSDT of some chemical compounds measured is very characteristic. Fullerence C₆₀ gives negative UVSDT peaks, the larger is the difference in temperature(∇t),the stronger is the intensity of negative UVSDT peak.
