DEPT-135 experiment using composite pulses
PRELIMINARY SET-UP
This is a simple modification of the DEPT-135 pulse sequence in which the last 180x 13C pulse is replaced by a 90y-180x-90y composite pulse. Thus, the user must be follow the same procedure as described for the above-mentioned experiment but using the deptcp135 pulse program.
PARAMETER SET
Create a new dataset with

The user can record this experiment from two different starting points:

  • Read the standard parameter set to record the DEPT-135 spectrum with rpar C13DEPT135 all document.write(getprosol);
  • Read the parameter set of the already-defined DEPT-135 experiment. This parameter set must be previously stored onto the disk.
    • Change the pulse program to deptcp135.
    MODIFY SPECIFIC PARAMETERS

    Change some of the following acquisition parameters if required: ns, ds, d1, d2, sw and td

    OTHER RELATED VERSIONS
    Once the parameter set of the DEPT-90 experiment using composite pulses has been defined, the analogs DEPT-45 using composite pulses and DEPT-90 using composite pulses experiments can be run simply changing the pulse program to deptcp45 and deptcp90 respectively. Otherwhise, a single parameter set can be defined (wpar deptcp all) for recording any DEPT experiment using composite pulses. In such case, the pulse program is set to deptcp and the user must define the corresponding p0 (45, 90 or 135 degree 13C observe pulse) according to the carbon multiplicity selection.
