The spiropyranâmerocyanine system was studied using ion mobility-mass spectrometry (IM-MS) and three major conformers were identified. Assignment of conformers is based on DFT-B3LYP energy minimized structures and collision cross-sections as light-induced changes in IM-MS. The three conformers were assigned to the spiropyran, cisoid and transoid structures.
使用离子迁移率质谱(IM-MS)研究了螺吡喃-氰胺系统,并确定了三种主要构象。构象的分配基于DFT-B3LYP能量最小化结构和碰撞截面,作为IM-MS中光诱导的变化。这三种构象被分配到螺吡喃、顺式和反式结构中。
