4. Estimate the transition frequency for the poryphyrin molecule from m-11 to m 12, assuming that the pi electrons can be modeled as a particle in a ring of radius 440 picometers. (C 7. The most probable distance of the electron from the nucleus in a 1ls state hydrogen atom (with wavefunction V1) can be determined by 21. A (A) solving the eigenvalue equation: Rvw rV., finding the maximum in the 1s radial distribution function by differentiation. (C) substituting vi, into the Schrödinger equation. D) finding by integrating [v/V,dr e ionization energy of the ground state hydrogen atom is IE(H). The ionization energy for the ground state of a one electron ion of nuclear charge Z is (B) IE(H). (A) IE(H). (D) Z IECH). (C) Z IE(H) Consider a variation of the one-dimensional particle-in-a- box problem in which a small perturbation is added to the system 19. 23 Perturbed system V(x) rr) = 0 for 0
