✦ Synopsis

Ten long-chain saturated and unsaturated alcohols were reacted with the ionic species [C 2 H 2 N] Y and [C 3 H 4 N] Y generated by ionization of acetonitrile into an ion trap. The mass spectra of the compounds under investigation show the formation of [M -H] Y , [M Y C 2 H 2 N] Y and [M Y C 2 H 4 N] Y ions in the case of saturated alcohols, whereas for monounsaturated and polyunsaturated derivatives additional peaks corresponding to [M Y H] Y and [M Y H -H 2 O] Y are observed. The reaction mechanisms were investigated by means of D-and 13 C-labelled acetonitrile. Collisional experiments were performed on the [M Y C 3 H 4 N] Y species from the polyunsaturated alcohols in order to identify any possibly diagnostic fragments for the identification of the double bond positions.
