本文研究了一系列具有良好结构的2-苯基乙硫醇金团簇的远红外光谱。星系团的光谱是不同的，但差异是微妙的。Au-S伸缩振动在300 cm（-1）及以下产生谱带。这些谱带的相对强度会发生变化，但对于不同的簇，它们只发生轻微的变化。一个低频带被确定，这是敏感的构象（反式/gauche）的2-苯基乙硫醇配体。
The far infrared spectra of a series of well-defined gold clusters covered with 2-phenylethanethiolate were studied. The spectra of the clusters are different but the differences are subtle. The Au-S stretching vibrations give rise to bands around 300 cm(-1) and below. The relative intensity of these bands changes but they shift only slightly for different clusters. A low-frequency band was identified, which is sensitive to the conformation (trans/gauche) of the 2-phenylethanethiolate ligand.
