报道了来自海绵 [Heteronemaecta] 的新二倍萜烯异酮素 (Heteronemin) (1) 的 13C-NMR 谱。大多数信号的分配是通过偏共振解耦、PRFT（部分松弛傅里叶变换）测量、与合适的已知模型化合物的比较和 LIS 测量的组合来完成的。根据 13C-NMR 数据，从 1 可以看出全反式-反式构型。
The 13C-NMR spectrum of heteronemin (1) a new sesterterpene from the marine sponge [Heteronema erecta] is reported. Assignment of most of the signals was accomplished by a combination of off-resonance decoupling, PRFT [partially relaxed Fourier transform] measurement, comparison with suitable known model compounds and LIS measurements. An all trans-anti-trans configuration is suggested from 1 according to the 13C-NMR data.
