Interpretation Introduction

Interpretation: The excited state that has higher energy should be determined.

Concept introduction: Two or more atomic orbitals overlap to form a bond, these orbitals are called molecular orbitals. Count of molecular orbitals generated is same as count of atomic orbitals mixed.

There are two forms of molecular orbital and that includes bonding molecular orbital and antibonding molecular orbital.

Bonding molecular orbitals are those in that electrons are in between the nuclei of two atom.

Antibonding molecular orbitals are those in which electrons are away from the nuclei of two atom. Also, electrons in antibonding orbitals have generally higher energy compared to bonding orbital.

In sigma (σ) bonding molecular orbital, electron density is shared directly between bonding atoms, along the bonding axis. In sigma (σ*) antibonding molecular orbital, the orbital is empty. In these molecular orbital’s electrons are along the nuclear axis.

In pi (π) bonding molecular orbital, bonding electron density lies above as well as below bonding axis and has no electron directly on bonding axis.

In pi (π*) antibonding molecular orbital, the orbital is empty. In these molecular orbital, electrons are perpendicular to nuclear axis.

If no, what is the expectation value? (b) Is σ an eigenfunction of S.? If yes, what is the eigenvalue? If no, what is the expectation value?
问题3 The 14 N160 molecule undergoes a transition between its rotational ground state and its rotational first excited state. Approximating the diatomic molecule as a rigid rotor, and given that the bond length of NO is 1.152 Angstroms, calculate the energy of the transition. As your final answer, calculate the temperature T in Kelvin, such that Eshermal = kBT equals the energy of the transition between NO's rotational ground state and first excited state.
Rotational spectra are affected slightly by the fact that different isotopes have different masses. Suppose a sample of the common isotope 1H35Cl is changed to 1H37Cl. (a) By what fraction is the molecule’s rotational inertia different? (The bond length is 0.127 nm in each case.) (b) What is the change in energy of theℓ = 1 to theℓ = 0 transition if the isotope is changed?
