Abstract
VCD spectroscopy was applied to allenic natural products to elucidate their axial chirality. The sign and intensity of CCC antistretching VCD signal were found to be affected by substituents on the allene.

Abstract
VCD spectroscopy in the 1900–2400 cm−1 region has less often been studied. This article briefly summarises VCD studies in this spectral region and discusses the properties of 1900–2400 cm−1 chromophores.
