Vibrational circular dichroism (VCD) spectroscopy was applied to study the stereochemical properties of a star-burst type tetranuclear Ru(III) complex, Δ-(or Λ-)[{Δ-(or Λ-)-Ru(III)(acac)(2)(taet)}(3)Ru(III)] (acac = acetylacetonato; taet = tetraacetylethanato). By comparing the VCD spectra of eight diastereomeric enantiomers, it was shown that the spectra reflected the homo- or hetero-chiral nature of the bridging part connecting the central core and the peripheral region.
振动圆二色性（VCD）光谱被应用于研究星爆型四核 Ru(III) 配合物Δ-(或 Λ-)[{Δ-(或 Λ-)-Ru(III)(acac)(2)(taet)}(3)Ru(III)]（acac = 乙酰丙酮酸盐；taet = 四乙酰基乙醇酸盐）的立体化学性质。通过比较八种非对映异构体的 VCD 光谱，表明光谱反映了连接中心核和外围区域的桥接部分的同或异手性性质。
