• Transient spectra and primary processes in the flash photolysis of CH3SSCH3, CH3SCH3, CH3SH and C2H5SH

  From direct observation of the CH3, CH3S, CH2S and S2 produced in the flash photolysis of CH3SSCH3(∼1950 Å) it was concluded that the primary processes are : [graphic ommitted] The relative degree of S—S to C—S bond scission was recorded as ∼1.35. The stability of CH3S and the instability of CH3SS are consistent with statistical partitioning of the excess energy. From the independence of the CH3S and CH3 on total pressure in the ∼1950 Å flash photolysis of CH3SCH3, it was concluded that the primary process is predominantly CH3SCH3+hν→CH3+CH3S. The stability of the generated CH3S is consistent with the statistical energy partitioning. By assuming equal yields of CH3 and CH3S radicals, the oscillator strength of the CH3S band at 2185 Å was 1.3(±0.2)× 10–3. Two primary processes were identified in the ∼1950 Å flash photolysis of CH3SH, [graphic ommitted] and the relative degree of C—S to S—H bond cleavage was 1:1.7. It was suggested that in this case the excited CH3SH finds a configuration in which the S—H potential is repulsive more rapidly than the rate at which the energy is partitioned. To account for the pressure dependent formation of CH3 and CH2S in the ∼1950 Å flash photolysis of C2H5SH, and also the independence of CH2S on added nitric oxide, the primary processes [graphic ommitted] were postulated.

  通过直接观察 CH3SSCH3（∼1950 Å）在闪烁光解过程中产生的 CH3、CH3S、CH2S 和 S2，可以得出结论：主要过程是......：[图略] S-S 与 C-S 键裂解的相对程度为 ∼1.35。CH3S 的稳定性和 CH3SS 的不稳定性与过剩能量的统计分配是一致的。 根据 CH3S 和 CH3 对 CH3SCH3 ∼1950 Å 闪光光解总压力的独立性，可以得出结论：主要过程主要是 CH3SCH3+hν→CH3+CH3S 。生成的 CH3S 的稳定性与统计能量分配一致。假设 CH3 和 CH3S 自由基的产率相等，2185 Å 处 CH3S 波段的振荡器强度为 1.3(±0.2)× 10-3。在 CH3SH 的 ∼1950 Å 闪光光解过程中发现了两个主要过程，[图形省略]C-S 与 S-H 键裂解的相对程度为 1:1.7。有人认为，在这种情况下，激发的 CH3SH 找到一种 S-H 势排斥的构型的速度比能量分配的速度更快。为了解释 C2H5SH 在 ∼1950 Å 的闪光光解过程中形成的 CH3 和 CH2S 与压力有关，以及 CH2S 与添加的一氧化氮无关，推测了以下主要过程[图略]。

  The ultraviolet absorption spectrum of the transient HS2 radical produced in the flash photolysis of H2S2 was recorded. The spectrum observed in the λ = 3070–3800 Å region is assigned to the Ã2A′ ← X2A″ electronic transition, and three progressions to the SS stretching (ν′1), SSz.sbnd;H bending (ν′2) and SH stretching (ν′3) vibrations of the 2A′ upper electronic state. Open-shell CNDO/2 calculations

  记录在H 2 S 2的快速光解中产生的瞬时HS 2自由基的紫外吸收光谱。在λ= 3070-3800的区域中观察到的光谱被分配给A 2 A'←X 2 A“电子跃迁，和三个级数到SS拉伸（ν' 1），SSz.sbnd; H弯曲（ν' 2）和SH拉伸（ν' 3）的振动2 A'上的电子状态。进行了开壳CNDO / 2计算，以优化基态（2 A''）的分子几何形状。为了比较，对HO 2基团也进行了类似的计算。HS在基态下，图2的弯曲并且在（2 A'）和（4 A '' ）的激发态下几乎是线性的。

  The infrared spectra of H2S2 and its 266 nm photolysis products are studied in an Ar matrix at 7.5 K. The antisymmetric and symmetric HS-stretching, and the antisymmetric bending of H2S2 are assigned at 2556.6, 2553.8 and 880.3 cm−1, respectively. The absorptions appearing during the photolysis at 2463, 2460 and 903 cm−1 are tentatively assigned to the HS2 radical. The two main dissociation channels

  在7.5 K的Ar矩阵中研究了H 2 S 2及其266 nm光解产物的红外光谱。H2 S 2的反对称和对称拉伸以及H 2 S 2的反对称弯曲分别为2556.6、2553.8和880.3 cm -1。暂时将在光解过程中出现在2463、2460和903 cm -1处的吸收归因于HS 2自由基。两个主要的解离通道为：H 2 S 2 + hν  →HS 2 + H和H 2 S 2 + hν  →S 2 + H 2，其分支比接近1。
