are observed in each case. The origin of these is considered, and it is concluded that the equilibrium configuration about the amino nitrogen is pyramidal and that there is a low-lying molecular “inversion” level. A vibration-rotation perturbation in the case of D2NCN indicates that for this molecule the level is about 15 cm−1 above the ground state.
摘要 已获得并分配同位素种类 H2NCN、HDNCN 和 D2NCN 的微波跃迁。在每种情况下都观察到了许多振动卫星。考虑了这些的起源,并得出结论,关于
氨基氮的平衡构型是
金字塔形的,并且存在低位的分子“反转”
水平。D2NCN 情况下的振动-旋转扰动表明该分子的能级比基态高约 15 cm-1。
