Try out the effect of several modes for DC correction available with 2D data. Load the raw data of the magnitude mode 2D COSY spectrum D NMRDATA GLUCOSE 2D HH GHHCO 001001.SER and choose no, quad and qpol as BC mod in F2. Note that usually for Fl no baseline correction is applied in the time-domain, i.e. BC mod (F1) = no. Fourier transform the data and store the individual spectra using ascending processing numbers. Compare corresponding rows to inspect the effect of different baseline corrections. [Pg.184]

Spin pinging [5.86] has been proposed as a method of using rectangular pulses in 2D homonuclear COSY experiments for tailored excitation. Using spin pinging it would be possible to select regions of overlapping multiplets which are not defined sufficiently in a standard 2D COSY spectrum because of the restricted number of data points. Probably... [Pg.264]

COSY pulse sequence (Figure 5A) and the 2D COSY spectrum of heptan-3-one with the ID spectrum plotted across the top (Figure 5B). The 2D spectrum contains a series of peaks along the diagonal whose positions in /"i and fi correspond to the positions of the peaks in the ID spectrum. Off the diagonal, cross peaks exist which correlate the frequencies of proton pairs which are coupled to each other. In COSY... [Pg.1205]
