Infrared spectra of carbocations and CH<sub>4</sub><sup>+</sup> in helium
Julia A. Davies, Shengfu Yang, Andrew M. Ellis
Abstract
Infrared (IR) spectra of rigid and fluxional carbocations have been measured at low temperatures (≤10 K) following electron ionization of superfluid helium nanodroplets doped with methane, and an IR spectrum for CH 4 + is presented for the first time.
