Hyperfine couplings and g-values for deoxyribose radicals^a

Compoundb	Hyperfine coupling constants (G)	g-Value (apparent)c
C1′•d
dAdo, 3′-dAMP	15.5 (1βH), 35(1βH)	2.0029
C3′•
dAdo, 5′-dAMP	21 (1βH), 28 (1βH), 40.5 (1βH)	2.0032
dAdo (pH ca. 12)	18.6 (1βH), 28 (1βH), 38 (1βH)	2.0032
C5′•
dAdo, 3′-dAMP, 5′-dAMP	∼21 (1αH)	2.0023

^a,bValues are for radicals at 77 K, formed by illumination at 143 K and at native pH (∼5), unless otherwise stated.

^cThe apparent g-value (experimental center of spectrum) is reported.

^dThese hyperfine couplings are identical to those found for C1′• in 3-dGMP (4).
