建立了一套用激光烧蚀制备金属化合物的装置，并用微波傅里叶变换研究了它们的转动光谱。变换（MWFT）腔光谱仪。已经研究的前三种化合物是氯化银、氯化铝（1）和氯化铜（I），它们是在氯气存在下，使用Q开关Nd：YAG激光器（532 nm）烧蚀银、铝和铜棒而产生的。 MWFT腔谱仪的高分辨率和灵敏度允许首次测定AlCl和CuCl的核自旋-旋转耦合常数。这些常数已被用来研究分子的电子结构。三种金属氯化物的转动和核四极耦合常数的值也得到了改善。
An apparatus has been constructed to produce metal compounds using laser ablation and to investigate their rotational spectra with a microwave Fourier. transform (MWFT) cavity spectrometer. The first three such compounds that have been studied are silver chloride, aluminum (1) chloride, and copper (I) chloride, produced by ablation of silver, aluminum, and copper rods in the presence of chlorine gas, using a Q-switched Nd:YAG laser (532 nm). The high resolution and sensitivity available with the MWFT cavity spectrometer have permitted the first determination of nuclear spin-rotation coupling constants for AlCl and CuCl. These constants have been used to examine the electronic structures of the molecules. Values of the rotational and nuclear quadrupole coupling constants have also been improved for the three metal chlorides.
