During the past decade or so, inorganic vibrational spectroscopy has made great strides with the advent of several new experimental techniques. First, the development of the metal isotope technique provided the means to make unequivocal assignments of vibrations in the low frequency region. It is currently a routine practice to obtain metal isotope data whenever definitive assignments of metal-ligand vibrations are required. Second, the matrix isolation technique became accessible to inorganic chemists as a result of the development and marketing of closed cycle helium cryocoolers. By combining various types of ovens with these cryocoolers, inorganic chemists were able to prepare a large number of unstable coordination compounds and measure their vibrational spectra in the matrix isolated state. Third, the development of gas and dye lasers together with double and triple monochromators revolutionized Raman spectroscopy. Nowadays, measurements of Raman spectra are as routine as that of infrared spectra. Resonance Raman spectroscopy is also playing a significant role in understanding the relationship between resonance-enhanced vibrational modes and the nature of excited electronic states involved. The purpose of this article is to review our contributions in these three areas using typical examples.
