摘要:

Vicinal JHHcouplings were investigated for a series of substituted dihydronaphthalenes allowing the conformation of the non-aromatic ring to be evaluated. It was found that the substitution of bromine for hydrogen increases the total puckering amplitude of the non-aromatic ring. Different formulations of the Karplus equation were investigated and the influence on the observed results are discussed.
