Effective relaxation rates for three different J-scaled TROSYHNCO experiments as a function of the scaled line position. Effective relaxation rates describe the decay of signal during the 15N evolution period (t2) according to S(t2) = S(0)exp[−Refft2], where the rates R2F and R2S refer to the rate of relaxation of the fast (upfield) and slow (downfield) relaxing components of the 15N doublet. The three experiments considered are: a The J-scaled TROSY-HNCO experiment of (Kontaxis et al. 2000) b The J-scaled TROSY-HNCO experiment of (Yang et al. 1999) and c The κnJ-scaled TROSYHNCO experiment described herein
