Diazo - Wikipedia
The electronic structure of diazo compounds is characterized by π electron density delocalized over the α-carbon and two nitrogen atoms, along with an orthogonal π system with electron density delocalized over only the terminal nitrogen atoms.
Structural and Chemical Biology of Terpenoid Cyclases
2017年8月25日 · Here, I review key advances in terpenoid cyclase structural and chemical biology, focusing mainly on terpenoid cyclases and related prenyltransferases for which X-ray crystal structures have informed and advanced our understanding of …

For example, there are two structural isomers with the molecular formula C3H7Br. In one of them the bromine atom is on the end of the chain, whereas in the other it’s attached in the middle. If you made a model, there is no way that you could twist one molecule to turn it into the other one.
6.7: ¹H NMR Spectra and Interpretation (Part II)
2021年12月16日 · As we have learned, there are a lot valuable information about the structure of a compound can be obtained from an 1 H NMR spectrum. For a summary, analyzing the four features of the spectrum is critical to elucidate the structure of a compound: The number of signals indicate how many different sets of protons there are in the molecule;
Conformational analysis of cycloalkanes | ChemTexts - Springer
2015年8月12日 · Cyclooctane is the smallest member of the class of medium rings. It exhibits all of the typical properties of a medium ring: difficulty in cyclizing, transannular strain, transannular reactions and lack of single lowest energy structure. A total of 10 different conformations have been identified [24, 25].
