APPLICATION FIELDS

The 119Sn NMR spectroscopy has been used almost always on organotin compounds due to sensitivity reasons ( 00PROG271 ). Solid state applications has also been reported.
NMR REFERENCES
A common external standard reference is SnMe4 in neat/benzene(absolute frequencies of 32.718749 MHz (115Sn), 35.632259 MHz (117Sn), and 37.290632 MHz (119Sn),with respect to 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).
NMR PARAMETERS
 Useful NMR parameters are:
NMR EXPERIMENTS
  • 1D 1H-decoupled vs 1H-coupled 119Sn spectra. Negative heteronuclear NOE is obtained due to the negative magnetogyric ratio. 1D 119Sn {1H} DEPT or INEPT experiments are usually recorded with improved sensitivity ( 90MRC755 ).
  • 1D and 2D 1H-119Sn HMQC and HMBC experiments ( 92MRC403 , 93JMRA249-102 , 94ORG1098 , 94PERK297 , 94ORG4026 , 96ORG1920 , 99ORG1699 , 00PROG271 ).
  • 2D and 3D 1H-117Sn J-Resolved HMBC experiments ( 00PROG271 , 02MRC65 ).
  • 2D 119Sn-119Sn EXSY experiment ( 94MRC617 ).
  • 2D 119Sn-13C correlation experiment ( 92ORG3481 ).
