| Abstract |
|
The use of an optical fiber guided light source in conjunction with a UV-Vis spectrophotometer to study the emission spectra of atomic hydrogen, sodium and helium in the undergraduate physical chemistry laboratory is described. The observed spectra have sufficient detail to allow an accurate calculation of the Rydberg constants and ionization energies of these elements. The obtained results also provide an opportunity to discuss energy level diagrams, selection rules for transitions, spin-orbit coupling magnitudes, and relative intensities of doublet lines.
