    • 2 cluster has two low-energy isomers within 1 kcal/mol of each other, one of them involving hydrogen bonding to iodide. Our previous model potential failed to properly reproduce this structure, and predicted instead a structure with two hydrogen atoms of the methyl group equidistant to iodide.

    • The CIS method was found to yield more reliable Franck-Condon energy gaps and dipole moments than time-dependent density-functional theory calculations (TD-DFT, and the multiconfigurational self-consistent field method CASSCF, given the basis set employed. Nonetheless, transition dipoles and associated oscillator strengths are qualitatively similar, regardless of the method employed
