Sample: Cyclosporine Solvent: C6D6 Spectrometer: AVANCE 500 Probehead: Inverse Broadband with z-Gradients Experiment: Magnitude-mode ge-2D COSY-DQF experiment Pulse program: cosygpmfqf ( Pulse Diagram) Experiment Time: 7 minutes Details: AVANCE Tutorial

The 2D ¹H-¹H COSY spectrum of cyclosporine help us in the assignment of the conventional ¹H spectrum by defining a series of some spin subsystems.

See list of spectra of cyclosporine

The concerted use of the 2D ¹H-¹³C HSQC correlation spectra greatly simplifies the assignment procedure.
