13C-HMQC-NOESY 

https://doi.org/10.1351/goldbook.08306
Three-dimensional nuclear magnetic resonance spectroscopy for the assignment of protein structure with one carbon and two hydrogen dimensions.
Notes:
  1. In the initial HMQC step, magnetization is transferred from A1A221H to A13A2213C and back again. This is then followed by a NOESY step in which the magnetization is transferred to any other hydrogen nucleus close by before detection.
  2. The technique requires A13A2213C labelling.
  3. The spectrum is used to obtain restraints for structure calculations.
