The absorption spectra of iron, chrome, manganese, zirconium, and industrial graphite, excited by a laser spark, were investigated with the use of intracavity laser spectrometer operating in the 1.06 micron region. C2 absorption spectra were identified and rotational lines of the transitions 3-0, 4-1, and 5-2 b3Σ-g - a3Πu, as well as 2-1, 1-0 A1Πu - X1Σ+g were determined.
