values of the 13 C chemicalshift tensor are presented for the three carbons in triphenylene and for three different α-carbons in phenanthrene. The measurements in triphenylene were made in natural abundance samples at room temperature, while the phenanthrene tensors were obtained from selectively labeled compounds (99% 13 C) at low temperatures (∼25 K). The principal values of the shift tensors were oriented
给出了联苯中的三个碳和菲中的三个不同 α-碳的 13 C 化学位移张量的主要值的测量值。苯联苯中的测量是在室温下在自然丰度样品中进行的,而菲张量是在低温 (~25 K) 下从选择性标记的化合物 (99% 13 C) 中获得的。位移张量的主值使用 ab initio LORG 计算在分子框架中定向
