On March 18, 2023, Prof. Jiang Ling, head of the Cluster Spectrum and Dynamics Research Group of the Dalian Institute of Chemical Physics, Chinese Academy of Sciences, was invited to give a report titled Research on the Structural Evolution Mechanism of Neutral Water Clusters in the lecture hall 1668 of Zhizhi Building.

Teachers and students of the Photonic Nose and Molecular Materials Group attended the meeting, which was chaired by Prof. Liu Jing.

Prof. Jiang Ling mainly engages in the research of cluster structure and dynamics related to atmospheric chemistry and energy catalysis, and has published more than 130 papers in Science, PNAS, JACS and other journals.

In the report, Jiang Ling said that the core key problem in the research of neutral water clusters is the development of quality selection and universal neutral cluster spectral detection methods. Based on a series of design concepts such as improving resolution and selective ionization of clusters, Jiang Ling developed the instrument, and realized the highly sensitive infrared spectral detection of selective neutral clusters in the gas phase through the combination of infrared excitation and ultraviolet ionization technology. He studied the evolution mechanism of water cluster structure, broke the inherent understanding that the smallest water droplet is composed of six water molecules, and discovered the new ice cube structure of the smallest molecule, which opened up a new path for the study of neutral clusters.

After the presentation, Jiang Ling interacted with the teachers and students present, answered their questions, and took a group photo with the participating teachers.
