Triatomic Hydrogen Molecular Overlaps
« on: October 14, 2014, 05:09:00 PM »
Just trying to draw the linear molecular overlaps of triatomic hydrogen. Not too sure how to draw the non-bonding orbital. Any ideas of how this should be drawn ? I can draw the bonding and antibonding orbitals fine, I have never heard of a non-bonding orbital until today.

Nonbonding MO for (linear) trihydrogen would likely have a node (no AO contribution) on the central hydrogen, positive and negative phase AO contribution, respectively, on the two end hydrogens.

Yes thats kind of the idea I was getting from other sources, thanks. Best off drawing it as the two AOs with a gap in the middle then. Much appreciated as always.

Quick question, do non-bonding MO's get labelled the same as bonding/antibonding MO's ? With parity and symmetry labels or is there  a separate label for NBMO's ?

Yes. A nonbonding orbital is just one that is neither stabilized or destabilized with respect to one or more of the constituent atomic orbitals.
