    Pulse sequences for detection of NH2···N hydrogen bonds in sheared G⋅A mismatches via remote, non-exchangeable protons

    The non-detectability of NH···N hydrogen bonds in nucleic acids due to exchange broadened imino/amino protons has recently been addressed via the use of non-exchangeable protons for detecting internucleotide 2hJN...

    Observation of internucleotide NH...N hydrogen bonds in the absence of directly detectable protons

    Several structural motifs found in nucleic acids involve N-H ... N hydrogen bonds in which the donor hydrogens are broadened to extinction due to chemical or conformational exchange. In such situations, it is ...

    Observation and measurement of internucleotide 2JNN coupling constants between 15N nuclei with widely separated chemical shifts

    Scalar coupling correlations between hydrogen bonded 15N nuclei in non Watson–Crick base pairs is a critical step in the structure determination of unusual nucleic acids. For observing the 2JNN coupling consta...
