Spectrum information

  Obs. freq. 162 MHz (Field = 9.4 Tesla)
  Pulse sequence single pulse
  MAS frequency 8-10 kHz
  Spectrum Digitized and processed by Brouwer Lab, Redeemer University
  Data processing Spectrum digitized with WebPlotDigitizer and deconvoluted with Mathematica notebook
 
  CommentPeak assignments are tentative since they are based on average bond angles determined from PXRD
