Typical parameters for 2D-DARR experiments.

MAS rate: 10 kHz (rotor period, τr = 100 μs)
Pulse	Power (kHz)	Duration (μs)	Phase
pH,1	110	2.27	(x)8, (−x)8
pH,2	Linear ramp between 40 and 80	2,000	y
pC,1	50	2,000	y
pC,2 (π/2)	50	5	x,−x and y,−y for each t1
pC,3	50	5	x,x,y,y,−x,−x,−y,−y
ϕReceiver	x,−x,y,−y,−x,x,−y,y,−x,x,−y,y,x,−x,y,−y
Delay	Duration (s)
d1	2
t1	varied for 2D acquisition
Mixing time	Duration (ms)
τ	10-1500
Decoupling period	Power (kHz)		Method
dec1	110		TPPM
Comments	During mixing, 1H continuous wave radio frequency should be applied with power equal to the MAS rotation rate (10 kHz).
