It is often used to approximate a Morse potential, whose horizontal asymptote is equal to the dissociation energy.
Second-order parameters for systems approximated by this model are often extrapolated from Birge-Sponer plots. The highly excited states of qubits have a larger Lamb shift than ac Stark shift because those excited states more closely resemble a pair of these systems coupled than the ground states. A more accurate model of microwave spectroscopy modifies B with a factor of minus alpha times the sum of one-half and this system's quantum number to account for this system's interactions with the rigid rotor. It is often used to approximate a Morse potential, whose horizontal asymptote is equal to the dissociation energy. One parameter that characterizes it may be found as the reduced mass times the square of the product of two pi, the speed of light, and the frequency in wavenumbers. This system's solutions consist of normalized Hermite polynomials weighted by a Gaussian, and may be derived by considering ladder operators. FTP, name this system, a quantum treatment of a system that obeys a quadratic potential thanks to Hooke's law.
