Description

For reference, see: Jump-and-return sandwiches: A new family of binomial-like selective inversion sequences with improved performance. T. Brenner, J. Chen, T. Stait-Gardner, G. Zheng, S. Matsukawa & W.S. Price, J. Magn. Reson. 288, 100 - 108 (2018). Double PFG echo sequences for selective suppression of NMR coherences. These pulse sequences have been prepared for spectrometers running Bruker's Topspin. The selectivity of the inversion pulse employed for a given total pulse time surpasses that of all published inversion pulses, including the commonly used W3 and W5. The pulse sequences employ Jump-and-Return Sandwiches with 6, 8, 10, 12 or 20 pulses. The sandwich is employed twice (hence, a double PFG echo is recorded). Title coding: zggpJRSN_NN: N indicates the total number of pulses in the JRS. NN, where stated, indicates whether the sequences belongs to Optimisation Set 1 or 2, as described in the original paper. For use of the pulse sequences, copy to the appropriate folder of Topspin. Note: certain versions of Topspin will not recognize imported files. A simple solution is to open a pulse sequence (e.g., zg), save it under a new name, then edit it (copy and paste the text from the file you wish to import).
