The 12937 cm^-1 band of Pt dimer has been recorded with rotational resolution using intracavity laser absorption spectroscopy. Based on Pt isotope shifts, this band is identified as the (1,0) band of an Omega =1 - alicsX Omega =1 transition. The results of the analysis will be presented and compared with previous work.
