How can we reach the NMR references of a nucleus?
Some references are on web pages, but most of them are in a mySQL data base.
There are three approaches to reach them:
- from the right-hand column of the home page, but some nuclei are missing, then via the MORE link to access to the data base;
- via the Periodic Table where all the quadrupole nuclei with half-integer spins are available;
- with the internal search engine via the SEARCH NMR references in a data base link to access to the data base.
What are the restrictions for MAS experiments due to the STATIC first-order quadrupole interaction during the pulses?
The pulse lengths should be short enough so that the MAS rotor could be considered to be static during the application of the pulses.
Why the second-order quadrupole interaction is not taken into account during the pulses?
If this interaction is present during the pulses, it means that it must be present during the acquisition of the FID. In this case, the lineshape analysis is applicable to extract the quadrupole parameters. Since the aim of the nutation nmr is to extract these parameters from a series of featureless lineshapes, which means that the second-order quadrupole interaction could be neglected during the pulses.
