Experiment Prototypes

Introduction

The experiment prototypes, also called Full Type, are accessed through M: Experiment: Experiment Prototypes:

The experiment prototypes describe NMR experiments; the magnetisation transfer pathway, what is being measured, and how the nuclei on the different axes are connected. Each experiment prototype groups a series of reference experiments that share a common magnetisation transfer pathway, but that can have different dimension and axes selection.

Experiment descriptions

The naming system of the experiment prototypes or Full Type are complex, but follow a systematic nomenclature; understanding what they mean and what your target experiment should be called is a great help. A detailed explanation can be found here, or at http://www.springerlink.com/content/h57q76k245r14558/. See the section for Full Type in this tutorial as well.

The best approach in finding the right experiment prototypes is to restrict the alternatives to a limited set of candidates and check the names and the detailed descriptions. Sorting on the |Name|, |Synonym|, or |Max Dim| can be a help. The |Category|, |Synonym| and |Keywords| columns serve to classify experiments, but can be incompletely filled in, or misleading. The R: Filter command is a good way to select sets of experiments; you might try filtering on ‘NOESY’, ‘TOCSY’, “CA”, “CO”, “H[N]” or “H[C]” (respectively 15N and 13C one-bond, out-and-back transfer), etc.

Other tabs in the Experiment: Experiment Prototypes popup

It is necessary to have a look at the other three tabs as well in the Experiment: Experiment Prototypes popup, to understand the experiment in detail:

• • The {Atom & Measurement} tab shows which atoms are on the magnetisation transfer pathway, and which properties (e.g. shifts etc) are being observed.

  • The {Exp Graphs} tab show the magnetisation transfers and the flow of magnetisation in the experiment.

  • The {Ref Experiments} tab shows the individual reference experiments and what is on the axes.
