Cyclobutadiene is an anti-aromatic molecule. What was your calculated HOMO-LUMO gap for cyclobutadiene? Would you expect this molecule to be paramagnetic or diamagnetic based on the calculated gap? The HOMO-LUMO gap I got using Webmo was 0.012 eV. 2. 11-cis-retinal plays a role in our vision. When an electron gets promoted it becomes easier to the cis-bond to rotate to the trans-isomer. What color light causes the promotion of an electron from the HOMO-LUMO for that molecule? 3. Pentacene has...
