From the output calculations the Homo value is (-7.513) and LUMO is (-3.335) so the calculated band gap was 4.17 ev . According to the following equation : Wavelength(in nm)=1240.8/Energy(in eV) = 297.55 nm My question is why I got this small wavelength 297.55 mm while the maximum wavelength from UV-VIS was above 500 mm ??

Provide brief definitions for the following: a) conjugation; b) polymer, c) HOMO and LUMO. 2) Why do conjugated compounds absorb light in the Ultraviolet region? Why do more conjugated compounds absorb at higher wavelengths/lower energies? What is required for organic compounds to absorb in the Visible light region?

What is the difference between Homo erectus / Homo ergaster and Homo heidelbergensis in terms of brain case (the part of the skull containing the brain)? Do you see any variations about the teeth between Homo erectus / Homo ergaster and Homo heidelbergensis? How does Homo erectus / Homo ergaster differ from Homo heidelbergensis in facial terms, including the jaws (and jaw projection)? Homo heidelbergensis is a species that is considered to be an evolutionary step closer to us (humans)...

Using a symmetry-based approach, construct a complete molecular orbital diagram for OH2. (a) Indicate the HOMO and LUMO. (b) Draw a representation of the HOMO and LUMO. (c) If one were to react this cation with another proton to give the dicationic species [H3O] + explain what would happen to the energies of the orbitals in the OH2 diagram after this reaction. Be specific about the key features regarding the M.O. diagram in the new cation. You do NOT need...
