^{a, b} The Kovats retention indices determined relative to a series of n-alkanes (C₁₀–C₃₅) on the apolar HP-5 MS and the polar HP Innowax capillary columns, respectively; ^c identification method: 1 = comparison of the Kovats retention indices with published data, 2 = comparison of mass spectra with those listed in the NIST 02 and Wiley 275 libraries and with published data, and 3 = coinjection with authentic compounds; t = trace (<0.1%).
