N2 - A study of the NMR lineshapes in solid D2 for various concentrations C of (J = 1) molecules is presented. Below the rotational ordering temperature Tλ (C), the lineshape has two doublets. The outer one, attributed to the J = 1 molecules, has a splitting of about 75 kHz for T ≪ Tλ. This splitting, which is proportional to the order parameter, was studied as a function of temperature. For the region 0.02 <1 - T/Tλ <0.08, the data could be fitted to a power law (1 - T/Tλ)β with β ≅ 0.33. The inner doublet was attributed to J = 0 molecules. Its splitting is proportional to Tλ (C) and is extrapolated to 8.5 kHz for C = 1 in good agreement with the prediction of Harris.
