¹³C CSA parameters for U-¹³C,¹⁵N Alanine recorded with various σ₂-CSA RN_n^v symmetry sequences.

			C′		Cα		Cβ
N	n	v	δσ (ppm)	ησ	δσ (ppm)	ησ	δσ (ppm)	ησ
14	2	3	68.5	0.87	21.9	0.60	13.5	0.65
18	2	5	68.4	0.77	22.2	0.58	14.1	0.75
10	1	3	69.6	0.80	21.2	0.72	14.3	0.62
12	1	4	67.7	0.74	22.5	0.52	13.2	0.97

¹Note: The MAS frequency was 10 kHz, and the rf field strength was 5N/n kHz for each RN_n^v symmetry sequence.
