Abstract The rotational spectrum of the HSiO radical has been measured in the millimeter- and submillimeter-wave regions. The radical is produced in a d.c. glow discharge plasma of a gaseous mixture of SiH4 and N2O. Molecular constants including magnetic hyperfine interaction constants of the hydrogen nucleus are determined accurately from the observed frequencies of 111 a-type R-branch transitions
摘要 在毫米波和亚毫米波区域测量了 HSiO自由基的旋转光谱。自由基是在 SiH4 和 N2O 的气体混合物的直流辉光放电等离子体中产生的。分子常数包括氢核的磁性超精细相互作用常数是根据 111 个 a 型 R 分支跃迁的观察频率准确确定的。一部分二次力常数来源于离心畸变常数和惯性缺陷,用于确定HSiO的零点平均结构;r 1 ( SiO ) = 1.5326(2) A 和 α1(HSiO) = 116.8(1)°,其中 r1(SiH) 假定为 1.5066 A。
