The spectra are characterized by broad asymmetric resonances that consist of an intrinsically broadened zero-phonon line which partially overlaps with the accompanying phonon wing. The band origin of the transition reveals a blue-shift of 116±84 cm-1 with respect to the corresponding gas phase transition. This blue-shift is suggested to be related to the presence of a relatively strongly bound high-density helium solvation layer around the ion.helium nanodropletselectronic spectroscopyanilinecationsuperfluiditytext::journal::journal article::research article
