title: Mobilities of Li(+)-attached butanol isomers in He gas.
abstract: Mobilities of Li(+)-attached butanol isomers, (n-BuOH)Li(+), (s-BuOH)Li(+), (i-BuOH)Li(+), and (t-BuOH)Li(+), in helium gas were measured over a range of reduced electric fields (E/N = 25-96 Td) at room temperature. Arrival time measurements accurately identified small differences in the measured mobilities of the isomer ions. At low E/N (≤30 Td, corresponding to a mean collision energy ε≤0.05 eV), (n-BuOH)Li(+) showed a mobility about 1.5% greater than that of the other ions, but at high E/N (≥75 Td, ε≥0.1 eV) its mobility was about 1.1% less.
