WebMenthone is one of the components of buchu oil and makes up about 10% of the mixture of volatiles. This figure shows spectral simulations of three conformers (A, B, and C) of menthone compared to the buchu oil broadband rotational spectrum. The spectrum simulations used the experimental fitted constants from Ref. [65].
