Ionization Loss/Gain Stimulated Raman Spectroscopy (ILSRS/ILGRS) is a powerful tool for the structural investigation of isolated molecules and clusters in the gas phase. With these methods, it is possible to investigate structurally relevant Raman active vibrations as well as the spectral range below 800 cm⁻¹, which is difficult to access with table top IR lasers in molecular beam experiments. Here, we present the first examinations with the newly installed ILSRS/ILGRS setup investigating diphenyl ether (DPE) and bisphenyldiadamantane (BPA) in the gas phase. This is the first application of the stimulated Raman technique on the class of diadamantanes, which is of great importance because of the extraordinary length of the connective C-C bond. In combination with dispersion-corrected DFT calculations we are able to receive a structural agreement of experiment and theory.
