Calling nonlinearity into question : When Ti atoms are isolated in fluorine‐doped argon matrices, TiF 4 , TiF 3 , TiF 2 , and TiF are identified by their IR spectra. The Ti isotope pattern observed for the ν 3 mode of TiF 2 is indistinguishable from that of a linear geometry. Therefore, there is now no reliable evidence for the nonlinearity of any 3d transition‐metal difluorides or dichlorides.
