TopSpin Training Course, 22
nd
November 2006
Overview
•Introduction to TopSpin
•Acquiring data through IconNMR
•Processing data
•Plotting/storing data
•Interpretation –a worked example
•Questions
What is the same?
•Before looking at the new features it is worth mentioning what
has not changedin TopSpin:
-Parameters and Data format: you can still process
TopSpin data with XWINNMR (not from AVII hardware)
-Most text commandsare either the same or aliased to the
equivalent TopSpin command (i.e. you still type efp, …)
-IconNMRhas a few new features, but broadly remains the
same –automation users will not need re-training, and
most will never notice any difference!
-XWINPLOTis essentially the same, so if you are already
using it in xwinnmr you are ready for TopSpin Plot Editor!
What is New?
•Integrated data browser
•Command line history (and concatenation)
•Configurable interface
•Full support for handling multiple datasets
•New interactive tools for Phasing, Integration, Peak Picking,…
•Interactive guides (acquisition, processing, relaxation,…)
•Acquisition status bar and tools
•Extendable via AU programs, Python programs, etc.
(including access to user interface)
• …and much much more!
Acquiring Data
•Sample preparation is key
•Selecting the right experiment:
-What information do you need?
-Which experiment(s) will give you this information?

An introduction to processing
•Most spectra run through IconNMR will be processed
(and perhaps printed) already
•You could simply open the processed spectrum and look at
the data
•You could reprocess -fundamentally:
-multiplier, Fourier transform and phase
(more on this later)
•Then you can integrate, peak pick, calibrate etc.

Processing 1D data
•Processing guide (automatic/manual)
-Processing -> Data Processing Guide
•Command line automatic: “xaup” –this will probably
also print a spectrum
•Command line manual: em, ft, apk/apks
•Button: if you have one set up….
…of course you could set one up…
Processing 2D data
•Processing guide (automatic/manual)
-Processing -> Data Processing Guide
•Command line automatic: “xaup” –this will probably
also print a spectrum
•Command line manual: xfb, abs1, abs2
•Button: if you have one set up….
… of course you could set one up …

Summary
•Think about data you need … don’t waste instrument time by
submitting every sample for all experiments
•Remember sometimes you can obtain C13 chemical shifts
from combination of 2D spectra when sample is limited
•Use processing guides !!
•Remember you can create a button for tasks you often repeat
•“Save” is implicit in TopSpin –any processing changes you
make will be remembered for next time
•“Prnt” gives you quick and dirty screen dump
•Plot Editor gives you pretty spectra for hard/electronic copy
• ………….any questions??
