~(13)C relaxation parameters of morphine in solution were measured at 90.1 and 62.9 MHz. An axially symmetric rotational model was applied to calculate the ro- tational rates.The calculated rotational rates are 8.6×10~9 revolution s~(-1) about the principal X-axis and 6.1×10~9 revolution s~(-1) about Y-axis.The N-CH_3 methyl internal rotation rate is 5.7×10~9 revolution s~(-1) and the internal rotation barrier is 4.59 kcal mo1~(-1).
