Just accepted in JASMS, we argue in this critical insight that in order to enable the development of new-generation CCS modeling software, interactions between ions and neutrals in multiple drift gases must be experimentally measured. Not only do these measurements show differences in ion-neutral interaction trends across molecular classes, but also will help define what computationally generated, energy minimized structure exists in the gas phase, as the ionic structure cannot change as a function of gas. This can be done by changing the polarizability of the gas, i.e. by changing the gas and mixing gases.
