[Question from NMRWiki Q&A forum] calculating power level with stdisp
calculating power level with stdisp
For some reason the shape tool has some sort of glitch that I can't calculate a power level for a wurst 10 ms pulse 180 rotation for a a 522 max gamma ~ for over 3000 Hz, with an option "Analyze adiabatic shape".
It insists it is not an adiabatic shape.
So I tried opening the same file shape tool in XWIN-NMR shape tool and the same problem occured but this time it gave me the Hz covered in maximum gamma when I included the degrees of rotation as well as the time for the pulse. it covers a 3ppm bandwidth etc.
I think I've done this many years...

[Question from NMRWiki Q&A forum] What is the optimal sample length with Shigemi tubes?
What is the optimal sample length with Shigemi tubes?
Our coil area length is 16 mm. Should we be making samples exactly 16 mm long in the Shigemi tubes for the best sensitivity (assuming that we are limited on amount of material)?
For example, we use D2O matched shigemi tubes for samples in 90/10 H2O/D2O. Is susceptibility matching affected by switch from D2O to H2O?
Thanks!

[NMR Geek blog] Chemical Shift Referencing Calculator
Chemical Shift Referencing Calculator
Below is the protocol I follow for chemical shift referencing (direct for 1H, and indirect for 13C and 15N). Actually I always have to look back and forth for referencing, so thought why not make a small script and put it on web so that the access becomes handy. !!! The referencing should be done
