  Weblink 13.2 HOMO for the trimethyl carbenium ion / OH- interaction

MO1 shows the interaction between the 2p AO on the central carbon and C–H s bonding MOs. The LUMO shows the same interaction, but in this MO the interaction is out-of-phase. Note that the LUMO is primarily located on the central carbon.
