There are some peculiarities associated with Bruker data. To accomplish quadrature detection using this scheme, the data is digitized at twice the rate and points are placed into the 2 channels alternately. In other words, the n th point placed into each channel are not acquired the same time. See example .
Sequential detection can cause a different artifact with similar appearance.
See example . If the data is complex, switching the channels simply reverses the spectrum. We have been unable to identify any header information to detect which channel is real and which is imaginary. An entry has been added to the NUTS.INI file which allows the user to automatically perform an RI on Bruker Aspect data at the time it is imported into NUTS, so that the user does not have to do this explicitly. If the line is not present in the INI file then add it, left justified as typed above.
