This problem considers the atomic term symbols and corresponding spectra a. determine the term symbols arising from the electron configuration npl. which of them correspond to the state with the lowest energy? b. determine the term symbols arising from the electron configuration nd. which of them corresponds to the state with the lowest energy? c. consider now the 2p and 3d energy levels of a h-atom i. based on your answers in part a. and b., in how many, and which states do the 2p and 3d levels split? sketch the ordering of these 2p and 3d energy states. ii. which transitions from the 3d states to the 2p states are allowed according to the selection rules for the atomic spectra? sketch these transitions ii based on the above, how many spectral lines will appear in the fine structure of the 3d 2p transition in the h-atom? d. two transitions, from two 3d states to the same 2p state have frequencies of де,-15 233.070cm-1 де, 15 233.034cm-1 respectively i. which are exactly the 3d and 2p states connected by these transitions? ii. based on i., determine the energy separation of the two 3d states involved in transitions note: for atomic spectra, the selection rules are as follows: but transitions between two states with j-0 are forbidden
