Namibia Opinion Revisited: A Gap In The Current Arguments On The Power Of The Security Council

This article discusses the interpretation of Article 25\u27 of the United Nations Charter that was offered by the International Court of Justice in its advisory opinion of June 21, 1971 (Namibia Opinion).2 It is a topic that is unfortunately overlooked by the current arguments concerning the power of the revived Security Council

Significance of Vibronic Coupling that Shapes Circularly Polarized Luminescence of Double Helicenes

Mori T., . Significance of Vibronic Coupling that Shapes Circularly Polarized Luminescence of Double Helicenes. Angewandte Chemie - International Edition 63, e202319702 (2024); https://doi.org/10.1002/anie.202319702.The circularly polarized luminescence (CPL) spectra of S- and X-shaped double helicenes exhibit distinct vibrational structures and overall shape variations. In this study, we conducted an in-depth investigation into the vibronic effects influencing the CPL spectra of two double helicenes, namely DPC and DNH. Employing state-of-the-art computations utilizing the FC-HT1|VH model at the CAM−B3LYP/def2-TZVP level, we unveiled the paramount impact of Franck–Condon (FC), Herzberg-Teller (HT), and Duschinsky effects on their chiroptical responses. Our research underscores the pivotal role of structural deformations associated with the S1-to-S0 electronic transition in molding CPL spectra and wavelength-dependent dissymmetry (g) factor values, as well as the significance of HT effects in shaping and enhancing CPL responses. This extensive investigation not only advances our comprehension of the vibronic characteristics in configurationally distinct double helicenes but also offers valuable insights for the design of chiral molecules featuring controllable or finely-tunable CPL responses
