Abstract
Correction for ‘Probing the photoabsorption features and electronic excited states of propylene oxide: an experimental and theoretical study’ by Mónica Mendes et al., Phys. Chem. Chem. Phys., 2026, 28, 7645–7654, https://doi.org/10.1039/D6CP00031B.
The authors wish to clarify and acknowledge the context of previously published work relevant to this study. In particular, the work by Garcia et al. (Sci. Adv., 2022, 8, eadd4614), cited in the original article, not only reports vacuum ultraviolet circular dichroism measurements of propylene oxide but also includes time-dependent density functional theory calculations of its electronic excited states, in particular vertical excitation energies and rotatory strengths.
The present work focuses on high-resolution VUV photoabsorption cross sections over an extended energy range and provides a more detailed characterization of the excited states based on TDDFT calculations, including excitation energies, oscillator strengths, and assignments derived from natural transition orbital (NTO) analysis. In addition, the evolution of the excited-state character along selected nuclear coordinates is explored, revealing Rydberg–valence mixing effects.
The authors acknowledge that the relationship between these studies could have been more clearly stated in the original manuscript and regret any lack of clarity in this regard.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
