A pulse sequence for localized in vivo (1)H NMR spectroscopy is presented, which selectively filters single-quantum coherence built up by strongly coupled spin systems. Uncoupled and weakly coupled spin systems do not contribute to the signal output. Analytical calculations using a product operator

## Abstract Protonβobserved carbonβedited (POCE) NMR spectroscopy is commonly used to measure ^13^C labeling with higher sensitivity compared to direct ^13^C NMR spectroscopy, at the expense of spectral resolution. For weakly coupled firstβorder spin systems, the multiplet signal at a specific prot
## Communicated by B. Brosowski We use the implicit function theorem to prove an existence of a heteroclinic orbit to a system of two non-linear second-order ODEs. The perturbation is carried out around infinite value of a 'coupling parameter'. The form of the system which is considered in this pa
