Abstract

The chemical shifts of (13)C in natural abundance have been obtained from nuclear magnetic resonance spectra of scyllo-, myo-, chiro-, and epi-inositols at 15.1 MHz. A set of empirical substitutent parameters were derived and shown to be moderately successful in correlating the (13)C resonance-line positions for these substances. The substituent parameters conform generally to the idea that steric hindrance or porximity effects are of special importance in influencing chemical shifts of carbons in cyclohexane systems.

摘要

天然丰度下(13)C的化学位移已通过在15.1兆赫下对scyllo-肌醇、myo-肌醇、chiro-肌醇和表肌醇的核磁共振谱获得。推导得到了一组经验取代基参数，结果表明这些参数在关联这些物质的(13)C共振线位置方面取得了一定成功。取代基参数总体上符合这样一种观点，即空间位阻或邻近效应在影响环己烷体系中碳的化学位移方面特别重要。
