摘要
从环庚-1,3-二烯(1)在300 MHz的光谱分析中得到的1 H N.m.r.耦合常数不符合先前提出的除一个碳原子外所有碳原子共面的Cs结构;相反，这些数据表明了C2对称的扭曲桶形构象。
Structure of cyclohepta-1,3-diene from nuclear magnetic resonance analysis
1 H N.m.r. coupling constants obtained from spectral analysis of cyclohepta-1,3-diene (1) at 300 MHz are not in accord with an earlier propose Cs structure in which all but one of the carbon atoms are coplanar; instead these data indicated a distroted tub conformation of C2 symmetry.
