“像素成像质谱”相机用于对空间中预排列的3,5-二溴-3,5-二氟-4-氰基联苯分子进行飞秒激光诱导库仑爆炸成像。该实验允许同时检测每个采集周期中多个分子碎片产生的所有离子碎片的相关二维动量图像。库仑爆炸研究提供了有关母体分子结构和碎片动力学的丰富信息，并为分子内过程的实时成像开辟了新的机会。
The “pixel imaging mass spectrometry” camera is used to perform femtosecond laser-induced Coulomb explosion imaging of 3,5-dibromo-3,5-difluoro-4-cyanobiphenyl molecules prealigned in space. The experiment allows the concurrent detection of the correlated two-dimensional momentum images of all the ionic fragments resulting from fragmentation of multiple molecules in each acquisition cycle. The Coulomb explosion studies provide rich information about the parent molecular structure and fragmentation dynamics, and open new opportunities for real-time imaging of intramolecular processes.
