The potential energy of interaction between two nonbonding atoms is sometimes modeled by the LenardJones (also known as the "612") potential:
Discuss, using a graph of the original and approximate functions, what we hope to accomplish by choosing to do this. To get the best approximation in the neighborhood of the minimum of the potential, what should we choose for V_{0}, k and r_{0}?
