The true standard error of difference is equal to the standard deviation of the entire sampling distribution of differences when all the sample pairs in the population have been measured.
Relative Energies
Comparative measure of the energy levels of molecules in different states or configurations.
π Molecular Orbitals
Orbitals formed by the overlap of p-orbitals across adjacent atoms, involved in pi bonding, crucial for the understanding of conjugated systems.
Occupied π Molecular Orbitals
π molecular orbitals that contain electrons; they are involved in bonding between atoms and are crucial for understanding the reactivity of molecules.
Cyclobutadiene
A highly unstable, conjugated diene with the molecular formula C4H4, characterized by a square planar structure that challenges classical bonding theories.
