TOCSY identicationTotal correlation spectroscopy (TOCSY) experiments (Table 2)were run on Melon Code Black (MCB) herbal incense (Fig. 4)and JWH-203 standard powder (Fig. 1, found in MCB), alongwith the other 11 herbs. TOCSY spectra incorporate interactionsbetween neighboring protons as well as longer range couplingsbetween protons on a chain or in a ring. Therefore, it is useful tolook at a COSY spectrum to discern between neighboringinteractions and longer range interactions in the TOCSYspectrum.
