PPT-Molecular Orbitals from 2p Atomic Orbitals

The 2p z orbitals overlap in headtohead fashion so these bonds are s bonds the corresponding MOs are s 2p and s 2p The other 2p orbitals ie 2p x and 2p y overlap in. (16.4-16.6). Solution of SE for molecules is more complicated due to much larger number of electrons and multiple nuclei. SE is still not exactly solvable since more than one electron is involved. Atomic orbitals are not appropriate since multiple nuclei are involved. Conceptual Reminders: Waves/Blackbody Radiation Energy. Example. A lamp rated at 40.0 J/sec emits violet light of wavelength 422 nm. What is the energy of the photons? How many photons of violet light can the lamp generate in 2.0 sec?.
