N2 - LAMIS is a known technique for isotopic shift analysis of light elements, such as B, C, etc. Its application for heavy molecules has been studied less. We proved that vibrational and rotational transitions A(1–0), A(1–2), and A(2–1) of GdO in Laser-Induced Plasma exhibit apparent differences between natural GdO, 156GdO, and 158GdO emissions. The absolute values are in the 0.4–0.5 cm−1 range. Besides its adequate spectral resolution, the Demon HR Double Echelle Monochromator proved its sensitivity for isotopic analysis of Rare Earth Elements.
