Fig. 5. The relationship between applied power to 1a : 1b (a) and % mass β-myrcene to 1a : 1b (b). 1a : 1b is calculated as the quotient of the selected ion chromatogram integrations of the molecular ions for 1a products, 3MCA (m/z = 84 amu) and 2M2B (m/z = 70 amu), with 1b products, isoprene (m/z = 67 amu) and 3M1B (m/z = 70 amu).
