The using molecular orbital theory to given which molecule is diamagnetic CO B 2 O 2 None of the above (all are paramagnetic) Concept Introduction: When a paramagnetic substance is placed in an external magnetic field, the magnetic fields of each atom align with the external field, creating the attraction. So, a paramagnetic substance is attracted to a magnetic field. While the electrons in an atom or molecule are all paired, the magnetic fields caused by electron spin and orbital angular momentum tend to cancel each other, resulting in diamagnetism. So, a diamagnetic substance is not attracted to a magnetic field.

Definition Definition Product of the moment of inertia and angular velocity of the rotating body: (L) = Iω Angular momentum is a vector quantity, and it has both magnitude and direction. The magnitude of angular momentum is represented by the length of the vector, and the direction is the same as the direction of angular velocity.

Concept Introduction:
When a paramagnetic substance is placed in an external magnetic field, the magnetic fields of each atom align with the external field, creating the attraction. So, a paramagnetic substance is attracted to a magnetic field.
While the electrons in an atom or molecule are all paired, the magnetic fields caused by electron spin and orbital angular momentum tend to cancel each other, resulting in diamagnetism. So, a diamagnetic substance is not attracted to a magnetic field.
Vibrational contributions to internal energy and heat capacity1) are temperature independent2) are temperature dependent
The approximation of calculating the partition function by integration instead of the summation of all the energy terms can only be done if the separation of the energy levels is much smaller than the product kT. Explain why.
Explain the meaning of: the electron partition function is equal to the degeneracy of the ground state.
