This study is concerned with the effects of applying selective simple product-operator formalisms, and ( iii ) in practical pulses to systems with strong second-order scalar couplings in applications of two-dimensional spectroscopy, it is often isotropic phase, where different transitions ( r s ) are associated assumed that strongly coupled pairs of spins merely lead with different transition matrix elements F / (rs ) . Two unusual to cross peaks that are close to the diagonal, and it is often features can be distinguished: the nutation angle ( ''flip angle'' ) believed that such features need not be taken into account. depends on the matrix element of the irradiated transition ( r s ) , In actual fact, none of these factors constitute a sufficient and, in contrast to the behavior of an isolated spin-1 2 system, reason for neglecting second-order effects: ( i ) even at the norm of the three single-transition operators [ I ( rs )

A novel multidimensional NMR pulse sequence tool, spin-state-selective time-proportional phase incrementation (S(3) TPPI), is introduced. It amounts to application of different TPPIs on the two components of doublets so that their frequencies can be manipulated independently. The chief application i
