PHYSICAL PROPERTIES
 

¹⁹⁵Pt NMR spectroscopy is applied on iInorganic and organometallic platinum-containing compounds. Some solid-state application have also been reported.

A commonly used external reference is 1.2M Na₂PtCl₆ in D2O ( absolute frequency of 21.496784 MHzwith respect to the 100.00 MHz of TMS). Also see IUPAC recommendations for reporting the NMR chemical shits of all nuclei relative to the ¹H resonance of TMS (02JMR323-156).

Some interesting features of the Pt nucleus are:

• ¹⁹⁵Pt chemical shifts cover about 15000ppm, ranging from +11840ppm ([PtF₆]^2-) to -3000ppm (Pt(0) and Pt(2) complexes).
• Short T₁ values.

In platinum-containing compounds the following experiments can be helpful:

• ¹H-decoupled vs ¹H-coupled ¹⁹⁵Pt spectrum.
• 2D ¹H-¹⁹⁵Pt HMQC experiment ( 88ORG2130 ).
• 2D ¹⁹⁵Pt-³¹P {1H} HMQC experiment ( 91MRCS11 ).
• 2D ¹³C-¹⁹⁵Pt correlation experiment ( 94CONC293 ).
• 2D ³¹P-¹⁹⁵Pt correlation experiments using phosphorus detection (( 91MRCS11 ).
