Question

We have chosen the convention that the zero of energy corresponds to isolated atoms in the ground electronic state, at rest. However, other choices of the zero of energy are possible. Suppose that the zero of energy is shifted by a fixed amount delta E_0, so that every energy E_j converts to the new value E_j + delta E_0. What is the effect of this shift on the partition function? What is the effect of this shift on the calculated value of the average energy? What is the effect of this shift on the heat capacity?

Explanation / Answer

a) Q = e-(Ej+E0) (Q is partition cofficient)

b) E = 1/Q( Ej+E0)e-(Ej+E0)

c) Ej+E0 = m×C×Q(m is the mass, c is specific heat, q is change in temperature)
