s being significantly underutilized. In our own work we have found that 13C spectroscopy is a more powerful tool than IH NMR spectroscopy, especially for probing subtle stereochemical questions in complicated systems. This is especially true in five membered ring compounds where IH NMR is at a parti分散 发表于 2025-3-24 09:31:40
Bicycloheptanes,ering of assigned numbers for the atoms adjacent to atom 1. Substituents that are oriented with this sense of rotation are defined as M (mit) while those opposed are G (gegen). For monosubstituted compounds, the numbering system is defined so that the substituent is M.municipality 发表于 2025-3-24 11:01:49

Fundamental Effects on Carbon Shifts,at, in most cases, the total effect on chemical shifts due to the presence of a large number and variety of substituents can be predicted to be the sum of the effects of the individual groups. It is this “substituent additivity” that sets carbon spectroscopy distinctly apart from proton spectroscopy喃喃而言 发表于 2025-3-25 00:14:45
Mono- and Bicyclic Systems,ch ring system has unique features and a relatively simple but “universal” set of Δδ values such as that found in Table 1–1 will be too general to provide accurate predictions for mono- and especially polycyclic systems. It is for this reason that we have gathered the extensive sets of carbon shift
