Scientists from the Pacific Northwest National Laboratory (PNNL) in the USA have studied the Raman spectrum of supercritical 18O-labelled CO2 and discovered that its vibrational modes were different to that of supercritical CO2 containing the more abundant 16O isotope. You can read a press release about the work from PNNL here.
