Excitation and correlation of 14N overtone transitions and measurement of heteronuclear dipolar coupling using DAPT

► A novel method for exciting 14N overtone transitions. ► Polarization transfer from proton ensures high sensitivity. ► Possibility of converting the pulse sequence as a 2D experiment built in. ► 14N-1H dipolar coupling and 14N-1H shift correlation information can be obtained from the same pulse sequence. ► Extends the use of 14N NMR spectroscopy.
