Spectrum information

  Obs. freq. 162 MHz (Field = 9.4 Tesla)
  Pulse sequence single pulse
  MAS frequency 10 kHz
  Spectrum Digitized and processed by Brouwer Lab, Redeemer University
  Data processing Spectrum digitized with WebPlotDigitizer and deconvoluted with Mathematica notebook
 
  CommentSpectrum was acquired with simultaneous 1H and 27Al decoupling. The two small peaks at 12.1 and 18.4 ppm are impurities. Peak assignments are based on a 2D 27Al/31P correlation spectrum.

Chemical Formula

  [Al - P - O]-AFN
