    • The initially-formed sodiated radicals are expected to be thermalized via collisions with the helium bath gas. Previous studies by Gronert suggest that ions in the QITMS are essentially at room temperature during ion-molecule reactions:

    • Radical stabilization energies (RSEs) and reaction enthalpies have been computed at the RMP2/G3MP2Large level of theory, with geometries and (scaled) ZPVE corrections determined at the B3-LYP/6-31G(2df,p) level. The RMP2 energies of the sodiated species were calculated with the inner-valence electrons on Na included in the correlation space (i.e., RMP2(riv)/G3MP2Large). A positive RSE corresponds to relative stabilization of the radical. For a recent discussion of RSEs, see:
