As a key precursor in the formation of new particles, sulfuric acid (H2SO4) plays an important role in the formation of aerosols and clouds in the atmosphere. Gas-phase sulfuric acid molecules can easily form molecular clusters at the beginning of nucleation through hydrogen bonding and other interactions. Therefore, study of the structure and spectroscopy of H2SO4 and tsulfuric acid–water clusters is of great significance for revealing the nucleation mechanism of new particles.
