Default NOESY peak signs

NOESY peak signs

I am new to NOESY, so I have a number of question about interpreting resulting 2D spectra. Mixing time is 300 ms, substance - lactic acid. I have a NOESY spectrum (pulse program - noesygphp) with several peaks having sign structure as:

- -+- - I know that the peak with the sign "-" corresponds to dipolar-dipolar interaction, "+" - to chemical exchange. But I don't understand what my result means.

Peak height versus peak volume
Given a standard NOESY-based protein structure determination: Does anyone have any information on the benefits of measuring peak intensity by a volume integration method rather than simply measuring the peak height. Obviously integration is theoretically more accurate, but does it make any difference to the quality of the structures produced? especially if peak lineshapes are comparable? I was hoping to find some study comparing structures produced by both methods..... I'm also curious about the benefits of distance-calbrating NOEs to a curve rather than simply putting restraints...

[Question from NMRWiki Q&A forum] Auto peak picking of N15Edit NOESY and C13 Edit NOESY spectrum
Auto peak picking of N15Edit NOESY and C13 Edit NOESY spectrum Dear friends, I am in process of doing structure calculation of a dimeric protein. The problem I faced is regarding the assignment of N15Edit NOESY and C13 Edit NOESY spectrum.I have already processed the fid data and converted to sparky ucsf format. Is there options available in sparky for auto peak picking, integration and assignment of my NOESY spectrum? And second query is regarding the generation of input files for structure calculation. In our Lab we are using ARIA 2.1 software for structure calculation? Is there any...

[U. of Ottawa NMR Facility Blog] E.COSY and the Relative Signs of Coupling Constants
E.COSY and the Relative Signs of Coupling Constants Spin-spin coupling constants can have values greater than or less than zero. The absolute sign of the coupling constants cannot be discerned from the simple examination of a 1H NMR spectrum. The E.COSY1 (Exclusive COrrelation SpectroscopY) technique is one method which can be used to determine the relative signs of coupling constants. E.COSY is a phase sensitive COSY variant which produces off-diagonal signals showing only the active coupling (i.e. the coupling directly responsible for the cross-peak) as 2x2 antiphase square tetrads...

Measurement of signs of chemical shift differences between ground and excited protein
Abstract Carr-Purcell-Meiboom-Gill (CPMG) relaxation dispersion NMR spectroscopy has emerged as a powerful tool for quantifying the kinetics and thermodynamics of millisecond exchange processes between a major, populated ground state and one or more minor, low populated and often invisible â??excitedâ?? conformers. Analysis of CPMG data-sets also provides the magnitudes of the chemical shift difference(s) between exchanging states (|Î?Ï?|), that inform on the structural properties of the excited state(s). The sign of Î?Ï? is, however, not available from CPMG data. Here we present...
