^aRetention index calculated experimentally on Rtx-5MS column relative to C8-C28 n-alkanes series.
^bCorresponding Kovats retention index from literature and spectral databases.
^cIdentification based on comparing retention indices (RI) and mass spectral data (MS) with those found in NIST Mass Spectral Library (2011), Wiley Registry of Mass Spectral Data (8^th edition) and reported in literature.
