Spectrum information

  Obs. freq. 161.2 MHz (Field = 9.3 Tesla)
  Pulse sequence single pulse
  MAS frequency 11 kHz
  Spectrum Digitized and processed by Brouwer Lab, Redeemer University
  Data processing Spectrum digitized with WebPlotDigitizer and deconvoluted with Mathematica notebook
 
  CommentPeak assignments are not available. It is important to note that two of the OH groups which bridge Al sites are not fully occupied. Tuel et al state that the OH groups are ordered along columns of cages, but that the order is not maintained between columns and therefore the strucutre does not possess long-range order.

Chemical Formula

  [Al - P - O]-ERI
