Study on the Stretching Vibration of Sulfur(S-S) by DRIFTS
摘 要
采用傅里叶变换漫反射红外光谱法，在500~400 cm-1范围内研究了单质硫S-S键伸缩振动红外吸收模式（νS-S）的一维漫反射红外光谱、二阶导数漫反射红外光谱、四阶导数漫反射红外光谱和去卷积漫反射红外光谱，并针对单质硫νS-S，进一步开展了相关二维漫反射红外光谱研究。结果表明：单质硫νS-S的红外吸收频率主要包括464，466，468，474 cm-1，而其红外吸收强度的变化顺序为464 cm-1>474 cm-1 > 468 cm-1 > 466 cm-1。

Abstract
A study on the sulfur S-S stretching vibration (νS-S) based on their one dimensional IR, 2nd derivative IR, 4th derivative IR and deconvolution IR spectrograms obtained by DRIFTS in the range of 500-400 cm-1 was made, and special attention was paid on the stretching vibration of sulfur by using the diffuse reflectance two-dimensional IR spectrograms. It was shown that νS-S appeared near 464, 466, 468 and 474 cm-1, and intensity of IR absorption of νS-S changed in the order of 464 cm-1>474 cm-1>468 cm-1>466 cm-1.
