An Overview of 195Pt Nuclear Magnetic Resonance Spectroscopy

Abstract

This brief, non‐exhaustive review describes some basic theoretical aspects of ¹⁹⁵Pt nuclear magnetic resonance spectroscopy and also the empirical approach used by the researchers in the field. The different factors which influence the chemical shifts are discussed. The couplings constants between ¹⁹⁵Pt and other isotopes, which have a spin of 1/2 (such as, ¹H and ¹³C) bring further important information on the structures of Pt compounds. Recently, ¹⁹⁵Pt‐NMR spectroscopy in the liquid state has been used successfully in many research fields, e.g., the determination of enantiomeric composition and absolute configuration, in the area of biosensors and biomarkers, in cluster chemistry, in cancer research and in kinetic studies. While liquid‐state ¹⁹⁵Pt‐NMR spectroscopy encompasses a wide range of areas, the parallel solid‐state technique has only been employed over the past few years, mainly in studies of heterogeneous catalysis and is more industrially oriented.
