摘要 我们通过分子束傅里叶变换微波光谱研究了自然丰度下噻唑- 33S 的 33S 核四极耦合。此外，还可以高精度分析 14N 核四极杆耦合。我们推导出旋转常数 A = 8529.29268 (70) MHz、B = 5427.47098 MHz 和 C = 3315.21676 (26) MHz、四次离心畸变常数和 33S 的四极耦合常数 χaa = 7.1708 (61) MHz 和 χbb= -26.1749 (69) MHz 且 14N χ aa = -2.7411 (61) MHz 且 χbb = 0.0767 (69) MHz。
Abstract We investigated the 33S nuclear quadrupole coupling of thiazole- 33S in natural abundance by molecular beam Fourier transform microwave spectroscopy. In addition the 14N nuclear quadrupole coupling could be analyzed with high precision. We derived the rotational constants A = 8529.29268 (70) MHz, B = 5427.47098 MHz, and C = 3315.21676 (26) MHz, quartic centrifugal distortion constants and the quadrupole coupling constants of 33S χaa = 7.1708 (61) MHz and χbb= -26.1749 (69) MHz and of 14N χ aa = -2.7411 (61) MHz and χbb = 0.0767 (69) MHz.
