The mass spectra of the trimethylsilyl derivatives of cis- and trans- hexahydrocannabinol and their hydroxy and acid analogues.

The mechanisms leading to the major ions in the mass spectra of the trimethylsilyl derivatives of cis- and trans-hexahydrocannabinol, five monohydroxy analogues, eight dihydroxy analogues, and two carboxylic acid derivatives were investigated with the aid of deuterium labelling and high resolution mass measurements.
