Abstract: The multidimensional NMR data acquisition on a routine spectrometer and processing on universal computer is described. The processing includes data format conversion, one, two and three dimensional NMR data processing programs, spectra display and plot program. The FFT formula for processing data obtained by sequence acquisition mode was derived, and other detail technical problems of developing the programs are discussed. As an example, H-H-C correlation 3D NMR spectrum of propyl alcohol is recorded and processed on VAX computer, the spectrum is displayed in Figure 1.

Key words: Data processing, Multidimensional NMR, Universal computer, Observation of 3D spectrum
