二甲基亚砜（DMSO）在低温固态氩基质中的紫外光照射产生次磺酸酯，CH 3SOCH 3，DMSO的高能结构异构体。在266 nm激光照射下，次磺酸酯分子进一步解离为CH 2 O-CH 3SH复合物。在紫外光照射下也会形成CH 2S-CH 3OH复合物。上述物种的红外光谱的基础上分配的同位素取代（C-13和氘），以及密度泛函频率计算。
UV light irradiation of dimethyl sulfoxide (DMSO) in low temperature solid argon matrix produces sulfenic ester, CH3SOCH3, a high energy structural isomer of DMSO. The sulfenic ester molecule further dissociates to the CH2O-CH3SH complex under 266 nm laser irradiation. The CH2S-CH3OH complex is also formed upon UV light irradiation. The infrared spectra-of the aforementioned species are assigned on the basis of isotopic substitutions (C-13 and deuterium) as well as density functional frequency calculations.
