Emission Spectroscopy of Sparklers. Lab Experiments using a solid-state computerized spectrometer that introduce students to analytical emission spectroscopy are described in the article "Emission Sepectrscopy in the Undergraduate Laboratory" by Scott R. Goode and Lori A. Metz on pages 1455-1459. In one of the experiments, molecular band emission is studied by obtaining the spectra of red, green, blue and gold sparklers, which show both atomic lines and molecular bands. Bands arising from salts of barium, copper, strontium, and sodium are responsible for the green, blue, red, and yellow colors seen in commercially abailable sparklers. The flames shown in the background were generated from solutions of BaCl2, CuCl2, SrCl2, and NaCl.
