The J = 1-0 to 4-3 spectral lines of SD+3 were measured in the 152-610 GHz region using a source-modulated microwave spectrometer. The SD+3 ion was generated in a free space absorption cell by a hollow-cathode discharge in a gas mixture of D2S and D2. The rotational constant B0 and the centrifugal distortion constants DJ and DJK were determined from the measured frequencies. A vibration-rotation analysis was carried out and the rz structures of SH+3 and SD+3 were derived from their zero point averaged rotational constants, expressed as SH+3: rz = 1.36512(22) Å and thetaz = 94.098(26) degrees, and SD+3: rz = 1.36086(16) Å and thetaz = 94.1211(195) degrees, where the difference between thetaz(HSH) and thetaz(DSD) was assumed to be the same as that between thetaz(HPH) of PH3 and thetaz(DPD) of PD3. From the shift between the rz structures of SH+3 and SD+3, the re structure of SH+3 was estimated to be re = 1.35001(113) Å, thetae = 94.181(135) degrees. Copyright 1998 Academic Press.

SD+3Ion 的微波光谱：分子结构

使用源调制微波光谱仪在 152-610 GHz 区域测量了 SD+3 的 J = 1-0 至 4-3 谱线。SD+3 离子是在自由空间吸收池中通过空心阴极放电在 D2S 和 D2 的气体混合物中产生的。旋转常数 B0 和离心畸变常数 DJ 和 DJK 由测量的频率确定。进行了振动-旋转分析，SH+3 和 SD+3 的 rz 结构源自它们的零点平均旋转常数，表示为 SH+3：rz = 1.36512(22) Å 和 thetaz = 94.098(26)度，和 SD+3：rz = 1.36086(16) Å 和 thetaz = 94.1211(195) 度，其中假设 thetaz(HSH) 和 thetaz(DSD) 之间的差异与 thetaz(HPH) 之间的差异相同PD3 的 PH3 和 thetaz(DPD)。从 SH+3 和 SD+3 的 rz 结构之间的偏移来看，SH+3 的 re 结构估计为 re = 1.35001(113) Å，thetae = 94.181(135) 度。版权所有 1998 学术出版社。
