Minimum labelling: ¹⁵N, ¹³C

Dimensions: 2

Magnetisation is transferred from ¹H to ¹⁵N via cross polarisation and then selectively to the ¹³Cα using specific cross polarisation. The chemical shift is evolved on the ¹⁵N nuclei and detected on the ¹³C nuclei.

This experiment can be used in the early stages of a project to assess the nitrogen line widths. It may also provide a means for assigning the nitrogen chemical shifts.
