羰基碘化金（OCAuI）是通过将金样品的激光烧蚀与含有一氧化碳和碘前体的气体的脉冲超声膨胀同步而在气相中产生的。傅里叶变换微波（FT-MW）光谱已被用来检测和分配线的纯转动光谱的分子。给出了三种同位素光谱中谱线的频率，并通过迭代最小二乘拟合确定了旋转、离心畸变和超精细耦合常数。旋转常数B 0的三个同位素异构体允许的r 0的分子几何形状的测定。结构是线性的。键长与OCMX配合物（M = Cu，Ag，Au; X = F，Cl，Br，I）的研究结果一致。最低能量的振动伸缩模式的频率估计从离心畸变常数的16 O 12 CAuI同位素。...='class10'>碘和金的核四极矩耦合常数，并对它们的核四极矩耦合常数进行了测定.
Carbonyl gold iodide, OCAuI, is generated in the gas phase through synchronizing the laser ablation of a gold sample with the pulsed, supersonic expansion of gas containing carbon monoxide and an iodine precursor. Fourier Transform microwave (FT-MW) spectroscopy has been used to detect and assign lines in the pure rotational spectrum of the molecule. The frequencies of lines in the spectra of three isotopomers are presented and used to determine rotational, centrifugal distortion and hyperfine coupling constants through iterative least-squares fitting. Rotational constants B 0 of the three isotopomers allow determination of the r 0 molecular geometry. The structure is linear. The bond lengths are consistent with previous studies of OCMX complexes (M = Cu, Ag, Au; X = F, Cl, Br, I). The frequency of the lowest energy vibrational stretching mode is estimated from the centrifugal distortion constant of the 16O12CAuI isotopomer. The nuclear quadrupole coupling constants of both iodine, , and gold, , have been...
