## Abstract Modifications of the BIRDβHMBC experiment, in which the accordion principle and a constant time period have been introduced, are presented. With the simple accordion BIRDβHMBC, the use of a BIRD^r, X^ element in the middle of the variable longβrange couplings evolution period efficientl
Signal enhancement in heteronuclear correlation spectra as well as signal selection in 1 H experiments can be achieved through inverse, i.e., 1 H, detection in the solid state under fast MAS conditions. Using recoupled polarization transfer (REPT), a heteronuclear 1 H-15 N single-quantum correlation
