In the COSY sequence 90° - t1 - 90° - FID(t2), cross peaks arise due to the evolution of J coupling between coupled spins. If the coupling between a backbone amide HN and its Hα is 10 Hz (ignoring relaxation), at what value of the t1 delay will the signal from the cross peak be most intense?
A. 200 ms
B. 100 ms
C. 50 ms
D. 0 ms
