Linear prediction has been introduced into the field of NMR spectroscopy as a valu-
able method of quantitative spectral estimation (1,2). Its applicability has been de-
monstrated even in case of broad band spectra with many narrowly spaced resonances (3
l_'.e, cases where LSQ curve fitting procedures (4) would seem to be unfeasible.
In the present study it is demonstrated that the application of the linear predic-
tion principle can be extended to include two dimensional NIIR spectroscopy, without
increasing the computation time drastically.
Examples are presented and the advantages as well as the pitfalls of the procedure
are discussed.
