Raw data pulse sequences and shapes for publication

## SEQUENCES ##
./sequences_renamed
Pulse programs introduiced in this work. Previous pulse programs can be obtained from https://doi.org/10.5281/zenodo.7016441 or https://optimal-nmr.net/experiments.html

## SHAPES ##
./shapes_renamed
TROP shaped pulses for homonuclear 13C-13C homonuclear mixing discussed in this work. Heteronuclear shaped pulses can be obtained from https://doi.org/10.5281/zenodo.7016441 or https://optimal-nmr.net/sequences.html

## RAW DATA ##
to decrease storage demands 3D-processed spectra were deleted and can be recovered using TopSpin command: ftnd 0
TopSpin NUS licence is required for processing of the NUS-sampled data. Transformed data can be obtained from authors on request.
