Abstract. An example and two exercises are presented that use hyperfine structure (HFS) to calculate the nuclear spin (I). The example uses the visible spectrum of a ¹⁸⁷rhenium(I) atomic emission at 527.7 nm. The spectrum of the rhenium(I) (⁸P_5/2 ® ⁶S_5/2) transition was recorded with a Fourier-Transform spectrometer with 0.026 cm^-1 resolution. This exercise for upper-level chemistry majors serves as an introduction to the coupling of the quantum momenta associated with the total electronic angular momentum (J) and I.
