  1. Consider the transition Ar (3p)6, 1S0 → Ar (3p)5 (4p), 1P1 Is it an allowed transition, and if not, why not? (A) allowed (B) not allowed, because no spin change (C) not allowed, because promoting a p-electron to another p-orbital (D) not allowed, because J=0 → J=1 (E) not allowed, because S → P

  2. Consider the transition Ar (3p)6, 1S0 → Ar (3p)5 (4p), 1P1 Is it an allowed transition, and if not, why not? (A) allowed (B) not allowed, because no spin change this would be allowed (C) not allowed, because promoting a p-electron to another p-orbital (D) not allowed, because J=0 → J=1 this would be allowed (E) not allowed, because S → P this would be allowed

  3. Consider the transition He (1s)(2p), 1P1 → He (1s)(4s), 1P1 Is it an allowed transition, and if not, why not? (A) allowed (B) not allowed, because n changes by 3, should change by ±1 (C) not allowed, because J=1 → J=1 (D) not allowed, because P → P

  4. Consider the transition He (1s)(2p), 1P1 → He (1s)(4s), 1P1 Is it an allowed transition, and if not, why not? (A) allowed (B) not allowed, because n changes by 3, should change by ±1 there is no rule for changing n (C) not allowed, because J=1 → J=1 DJ = 0 is allowed, as long as it’s not J=0 →J=0 (D) not allowed, because P → P DL = 0 is allowed

  5. After solving the electronic problem for H2+ within the BOA, we obtain the electronic energy eigenvalues E(R) as a function of the internuclear distance R. Now, we want to solve the problem of nuclear motion. What is the Hamiltonian for this problem? (A) where the problem is reduced to a one-particle problem with the reduced mass µ and the corresp. 1-particle Laplace operator (B) (C) (D) both (A) and (B) are correct formulations
