Jeener-Broekaert nuclear magnetic pulse sequences have been applied to solid hydrogen for ortho concentrations less than 50%. These measurements have been made at 4.2/sup 0/K and to temperatures as low as 0.45/sup 0/K. Below 1/sup 0/K for the time tau longer than the free induction decay multiple echoes have been observed. These are the first quantitative verifications of the predicted relative echo amplitudes and decay constants in any material. Spin lattice relaxation measurements in the rotating reference frame at 4.2/sup 0/K are presented. These are the first measurements in the rotating frame in the concentration range 10% to 50% ortho hydrogen.
