Five Decades of Dispute: A Triptych. E. J. Corey

open access: yesThe Chemical Record, EarlyView.
In his 2004 Priestley Medal address, E. J. Corey stated, “On May 4, 1964, I suggested to my colleague R. B. Woodward a simple explanation involving the symmetry of the perturbed (HOMO) molecular orbitals for the stereoselective cyclobutene/1,3‐butadiene and 1,3,5‐hexatriene/cyclohexadiene conversions that provided the basis for the further development ...

Coronal Magnetometry with EUV Permitted Lines

open access: yesThe Astrophysical Journal
A major challenge in solar physics is to obtain empirical information on the magnetic field of the million-degree plasma of the solar corona. To this end, we need observables of the solar radiation sensitive to the coronal magnetic field.

Water and hydroxyl on asteroid Bennu: Reconciling remote observations with OSIRIS‐REx sample analysis

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract This study investigates the spatial distribution and spectral characteristics of the broad hydration feature near 3 μm across the surface of asteroid (101955) Bennu using OVIRS (OSIRIS‐REx Visible and InfraRed Spectrometer) data. We analyzed multiple global OVIRS data sets obtained at different times throughout the Bennu day, revealing ...
