Abstract
Mass-resolved excitation spectra of the (2p3s)←(2p) 2 Rydberg transition of 1,4-diazabicyclo[2.2.2]octane (DABCO) clustered with polar and nonpolar solvents are reported. The DABCO /solvent clusters are generated in a supersonic expansion. The solvents employed in this study have diverse electronic and dipolar properties and include amines, ethers, aromatics, acetonitrile, a thioether, cyclohexanes, ethylene, N 2 , and Kr. The spectra can be analyzed in terms of cluster transition origins, van der Waals vibrational modes, and internal DABCO vibrational modes. Potential energy calculations are performed for the cluster ground state using atom-atom potentials
