It is best not use automated baseline correction before at least two dimensions have been transformed. Same with LP ... also, best not to use LP until all the

[Question from NMRWiki Q&A forum] same parameters but difference in phase why?
same parameters but difference in phase why?
hi, though this question seems to be easy for you but i am new for this software and to this field. Recently, i took silicon spectra in 500mhz(bruker) seems to be good (i.e.one silicon peak and one nmr tubes broad peak) but when i used same parameters for another sample where i got single peak as i expected but nmr tube peak is inverse this time. I just copied previous parameters only why i got such a inverse signal.If anybody know please help me.
thank you
Check if somebody has answered this question on NMRWiki QA forum

[U. of Ottawa NMR Facility Blog] First-Order Phase Errors
First-Order Phase Errors
The phase of a signal in an NMR spectrum is described here and is determined by the axis on which the magnetization vector resides after the observe pulse relative to the receiver. The phase of the spectrum is typically corrected such that the peak in the real spectrum is entirely in absorption mode while that in the imaginary spectrum is entirely in dispersion mode. The correction in phase is referred to as the zero-order phase correction. A zero-order phase correction applies to all peaks in the spectrum regardless of their offset, ?, from resonance. There are...

[U. of Ottawa NMR Facility Blog] The Phase of an NMR Spectrum
The Phase of an NMR Spectrum
Most students know that the phase of an NMR spectrum has to do with the degree to which the NMR resonances are above or below the baseline of the spectrum (i.e. the amount of absorption and dispersion character). Most students have also learned that the phase of a periodic time domain function depends only on the value of the function at time zero. Thus, the only difference between a cosine and a sine function is where the function starts at time zero. A sine is said to be 90° out of phase with respect to a cosine. Many students do not understand the connection...
