Implementation

Proton to Carbon CP followed by scalar coupling modulated homonuclear mixing with rSNOB soft pulses and independent SPINAL decoupling periods during mixing and acquisition.

All needed files were catenated together, and so must be separated. The file CTUC_COSY.acq is the first block of text after the author contributions. CTUC_COSY.s begins with

name "2D_CC_shell";

and ends with

return;

The next several files should be separated and placed in /export/homes/USERNAME/pulse_sequences/cpc/includes. Each new file begins with a long comment section. The files acq.inc, CTUC_COSY.acq, CTUC_COSY.s, rSNOB_063108.inc,rSNOB_delay2.inc, SPC5.inc, SPINAL1.inc, SPINAL2.inc, STANDARD_PARAMS, std_errs.inc, t1.inc, t2.inc, TAN_CP.inc, and TWO_D.inc should be created from this file.

CO-CA Version

The hard pulse version of the experiment can be used if soft_pulse_flag=0 and ipap_flag=0.

Aliphatic Version

The soft pulse version of the experiment can be used if soft_pulse_flag=1 and ipap_flag=0.

CACO IPAP (IP) Version

The IP version of the experiment can be used if soft_pulse_flag=0 and ipap_flag=0, with the carrier placed on resonance with the Carbonyl frequency.

CACO IPAP (AP) Version

The AP version of the experiment can be used if ipap_flag=1 (independent of soft_pulse_flag), with the carrier placed on resonance with the Carbonyl frequency.
