The main objective of Weblab is to reveal type and geometry of internal molecular motion due to its effect on the NMR spectrum. This is most evident in the intermedate case, where timescale of motion and NMR frequencies are comparable, but also very distinct in the fast-motion limit.
In the first case the spectrum is affected as a whole in a rather complicated way, while in the other case motion only affects the two quantities δ and η (see topic ⇒ Tensor Values and Notation).
The function Tensor Plot takes advantage of this. It allows to show δ and η as well as the 3 principal values of the averaged tensor as a function of a variety of process parameters like cone angle θ, jump angle φ and others. This provides a general view on the way, how certain types of motion are influencing the effective interaction tensor and hence the spectrum.
Typical results are:
