We discuss the symmetries, the behavior of the diabatic energy curves, as well as the static aspects of vibronic interaction for diatomic molecules in the presence of a strong magnetic field. Our central subject of investigation is the topology of the adiabatic electronic potential energy surfaces o

It was found that the oxirane ring is a functional group amenable to chiral discrimination by dirhodium-MTPA complexes. Considerable signal shifts up to 0.7 ppm are observed for 1 H nuclei close to the rhodium atoms in the complex. In analogy to previously reported olefins, this method appears to be
The 1H NMR spectra of a variety of chiral racemic nitriles were recorded in in the absence CDCl 3 and presence of dirhodium tetra-(R)-a-methoxy-a-(triΓuoromethyl)phenylacetate MTPA 4 MosherΓs [Rh 2 (MTPA) 4 ; acid]. Moderate 1H signal shifts but clear diastereomeric dispersions due to complexation w
Since the classical treatment by Torrey in 1949 of the problem of how magnetization evolves in a continuously applied B radiofrequency field, the topic has 1 received relatively little attention in the nuclear magnetic resonance literature. This article focuses on the behavior of the macroscopic mag
