3 13 Basic concepts fortwo- dimensional NMR ,QWURGXFWLRQThe Basic ideas of two- dimensional NMR will be introduced by reference tothe appearance of a COSY spectrum; later in this lecture the productoperator formalism will be used to predict the form of the NMR spectra (one- dimensional spectra) are plots ofintensity vs. frequency; in two- dimensional spectroscopy intensity is plottedas a function of two frequencies, usually called F1 and F2. There are variousways of representing such a spectrum on paper, but the one most usuallyused is to make a contour plot in which the intensity of the peaks isrepresented by contour lines drawn at suitable intervals, in the same way as atopographical map.
