CBD is legal in the United States and parts of Europe, as well as in some Asian nations such as Japan and Thailand. In a non-deuterated sample, each peak would be a doublet with a Jax-eq of approximately 13 Hz. In dinuclear systems, it is not uncommon for a carbonyl or alkoxide ligand to switch between a bridging and terminal position.

While prescription CBD is safe when used as directed, other forms of the molecule come with risks. Instead, print the problem out, find a solution that fits the data and then come back to this page. At this point, the lifetime of a species as axial or equatorial is much shorter than the time scale of the experiment (flipping the nuclear spin and observing the relaxation).
In November, a veteran social worker questioned in Chinese-language newspaper Ming Pao whether Hong Kong's government had a solid basis to correlate CBD with drug abuse or if it was simply following the mainland's lead.
