摘要

he electronically excited A and C;It has been observed that the unprotonated ammonia dimer exhibits peculiar behavior, compared to the larger ammonia clusters. In Chapter 4, we study the formation of the unprotonated ammonia dimer by excitation through the A state. Additionally, ab initio calculations were performed to give additional insight as to the structure and energies of the unprotonated dimer. Our experiments have revealed that after excitation to the A state, a fraction of the ammonia dimer clusters decay via predissociation, and the remainder undergo a proton transfer reaction and rearrange to an internally protonated Zwitter ion structure.;Ammonia clusters excited to the C;The experiments conducted in our laboratory and described in Chapters 6, 7, and 8 examine the multiple ionization dynamics and the phenomena of Coulomb explosion of clusters irradiated with intense laser fields. Charge states of up to
