Abstract The microwave spectra of five isotopic species of aminoborane have been observed. The rotational constants, centrifugal distortion constants, and nuclear quadrupole coupling constants of 11B and 14N were determined from the spectra. The planarity and symmetry of the molecule were confirmed by the measurements of inertia defects, dipole components, and statistical spin weight due to the four
摘要 观测了五种氨基硼烷同位素的微波光谱。11B 和 14N 的旋转常数、离心畸变常数和核四极耦合常数由光谱确定。分子的平面性和对称性通过惯性缺陷、偶极子分量和由于四个氢核引起的统计自旋重量的测量得到证实。由旋转常数确定的完整 rs 结构为: r (BN) = 1.391(2) A , r (BH) = 1.195(4) A , r (NH) = 1.004(2) A , ∠HBH = 122.2(2) )°,且 ∠HNH = 114.2(2)°。
