High‐resolution Stokes and anti‐Stokes Raman spectra of isotopically pure 127 I 79 Br were recorded with excitation by argon ion laser radiation using CCD camera detection and a scanning multi‐channel technique. The observed spectra show a complex rotational–vibrational structure, which can be explained in terms of Q branches, S band heads, unresolved O branches and corresponding hot band transitions. The spectral band shapes of the fundamental vibrational transitions and of several overtones were studied as a function of laser power and excitation wavelength. A symmetry principle between Stokes and anti‐Stokes spectra is also demonstrated. In addition, hyperfine structure in the electronic Raman spectra of atomic 127 I and 79 Br was observed under high resolution.
