"wadenoesygpph_ndec.mpp" is the WADE-NOESY pulse sequence in Bruker format. The shape files are listed below.
| Short Name | Full Shape Name | Operation Type | Pulse Length factor | Pulse Length | Amplitude | reference JBNMR (2022) |
|---|---|---|---|---|---|---|
| W1F90 | wadepi2x_rf0.00_25.700p1_bw1.85B1.mrf | WADE-π/2 | 25.7 | 25.7*40us=1028 us | 6.25kHz | Figure 5 |
| WR4 | wadepix_NP_2_rf0.00_34.595p1_bw0.82B1.mrf | WADE-π/2 | 34.595 | 34.595*40us= 1383.8 us | 6.25kHz | Figure 5 |
Bandwidth can be tuned by changing the RF power, the correponding pulse length is calculated by multiplying the 90 degree pulse length with the pulse length factor for each pulse.
consider the 'wadepi2x_rf0.00_25.700p1_bw1.85p1.mrf' shape,
for RF amplitude 25kHz (=> 90 pulse length = 10us), pulse length = 25.7*10us = 257 us
for RF amplitude 12.5kHz (=> 90 pulse length = 20us), pulse length = 25.7*20us = 514 us
