The photodissociation dynamics of OCS near 214 nm for the S(${}^1{D}_2$) channel were studied using velocity map ion imaging. Earlier studies at this wavelength were extended with new measurements of vector correlations and reanalysis of the rotational distributions in the υ= 0 and υ= 1 CO products. The results were employed to identify the contributions of the 2¹${\text{A}}^{\prime }$ (A) and 1${}^1{\text{A}}^{\prime \prime }$ (B) electronic state absorptions in OCS to the population of each CO final state. The contributions of the 1${}^1{\text{A}}^{\prime \prime }$ (B) state to the CO (υ= 1) population was found to be $\sim 2.5$ times smaller ($f_B=0.14\pm 0.04$) than previous theoretical estimates, and that to the CO (υ= 0) distribution $\sim 1.7$ times smaller ($f_B=0.20\pm 0.04$). A similar analysis was applied to experimental rotational distributions from the literature at photolysis wavelengths of 223 nm, 230 nm, and 248 nm.

S（）的OCS在214 nm附近的光解离动力学${}^{\mathrm{1个}}{d}_{\mathrm{2个}}$通道使用速度图离子成像技术进行了研究。通过矢量相关性的新测量以及对υ = 0 和υ = 1  CO乘积的旋转分布的重新分析，扩展了该波长下的早期研究。结果用于确定2 ¹的贡献。${\text{一个}}^{\prime }$ （A）和1${}^{\mathrm{1个}}{\text{一个}}^{\prime \prime }$（B）OCS中电子态对每个CO最终态的吸收。1的贡献${}^{\mathrm{1个}}{\text{一个}}^{\prime \prime }$（B）发现CO（υ = 1 ）的状态为$〜2.5$ 倍小（$F_{乙}=0.14\pm 0.04$），而不是先前的理论估算值，即到CO（υ = 0）的分布$〜1.7$ 倍小（$F_{乙}=0.20\pm 0.04$）。将类似的分析应用于文献中在223 nm，230 nm和248 nm的光解波长下的实验旋转分布。
