NMR Relaxation Rate Calculator (simple version, 15N only)

Calculate 15N R1, R2, and heteronuclear NOE rates from 1H-15N dipolar coupling and 15N CSA:

B0 field (MHz):

R2 from exchange (Rex, s-1):

N-H bond length (default: 1.02 Å, alternative: 1.04 Å):

15N CSA (x 10-6, default: 160, alternative: 176):

Rotational correlation time (ns):

Order parameter (S2, 0 - 1):
