Molecular structure of a left-handed double helical DNA fragment at atomic resolution. 
Nature, 282, pp. 680 - 686, 1979.

Experimental Information:

X-RAY DIFFRACTION

Space Group:

P 21 21 21

Cell Constants:

a = 17.87   b = 31.55   c = 44.58 (Ångstroms)

α = 90.0   β = 90.0   γ = 90.0 (degrees)

Refinement:

The structure was refined using the NUCLSQ program. The R value is 0.14 for 15000 reflections in the resolution range 0.0 to 0.9 Ångstroms with Fobs >  0.0 sigma(Fobs) and with I >  2.0 sigma(I)
