Physical Chemistry Questions: 3. Write down the simplest appropriate LCAO (linear combinations of atomic orbitals) variational wavefunction and give the explicit expressions for the atomic orbitals used, i.e., how they depend on the coordinates. 4. Write down the variational formula for the energy and give explicit expressions for the integrals that have to be computed. Don’t compute all the integrals, as it is too time consuming, but point out which are easy to evaluate and which are equivalent. Give an...

Prepare a skills audit for yourself. Ask yourself the following questions and write down your answers. What are the skills you wish to develop? How are you going to develop them? What action needs to be taken? What time frame is required? Select one of the development skills which you have identified and develop a professional development program that will provide the necessary training. Document your plan (220–250 words) and provide reasons for the professional development strategies you have chosen.
