Near‐IR Fourier transform (FT) Raman spectroscopic measurements were performed at high pressures for the first time by mounting a diamond‐anvil cell on the optical stage of an FT‐Raman microprobe equipped with a long‐range 4 × objective and by using a near‐IR (Nd: YAG, 1064.1 nm) laser to excite the sample. The utility of this new pressure‐tuning Raman microspectroscopic method was demonstrated by its successful application to a typical organometallic complex, Cr(CO) 4 (bipy)(bipy = 2.2′‐bipyridyl), which decomposes under conventional visible Raman spectroscopic conditions.
