1 - Import data file

The NMR processing program RMN(fat) is available from the web site of P. J. Grandinetti. It is for Macintosh computers. We use the 1.2.1d version despite a newer one is available.

We describe the procedure for processing the 3QMAS NMR data of ²⁷Al (I = 5/2) in a powder of aluminum-acetylacetonate, acquired with a Bruker 400 MHz NMR spectrometer. The experimental conditions and the two-pulse 3QMAS program are available from this site.

(1) We import the MQMAS NMR file by selecting the menu items:

File/Import.../Bruker (Long Integer)

and by selecting the file (e.g. nom.ser) in the open-file dialog window.

(2) We activate the checkboxes of Import Bruker Data File panel:
