Abstract

An interactive technique for the evaluation of cross-peak volumes in 2D-spectra is presented, based on a 1D nonlinear curve-fitting procedure. The effects of applied window functions, truncation of time domain data and cross-peak overlap on the evaluated cross-peak volumes are considered. The technique is applied to crowded NOESY spectra of the 34–65 and 163–231 fragments of bacterioopsin ofHalobacterium halobium. For these spectra 284 and 546 cross-peak volumes were measured with high accuracy.
