Dunning basis sets orbital energy calculations using

Figure 4.20a Application of the Jacobi transformation and the canonical orthonormalization procedure to the calculation of the Is orbital energy in hydrogen using the Dunning (4s 2s) Gaussian basis (46). Note that the calculation returns a second set of coefficients in cells H 22 and H 23, which are simply a product of the calculation procedure and give rise to a primitive approximation to the 2s orbital (22).
