An alcohol solution of benzotrichloride was introduced into vacuum as a continuous liquid flow (liquid beam) and was irradiated with nanosecond (∼5 ns) and femtosecond (∼200 ns) lasers at the wavelength of 274 nm. Ions produced by multiphoton ionization in the liquid beam and ejected from it were analyzed by a reflectron time-of-flight mass spectrometer. The ions produced were assigned to chloroalcoxybenzyl ions, C6H5CCl-(OR)+, and dialkoxybenzyl ions C6H5C(OR)2+. A trace amount of C6H5CCl2+ was observed as well. The mass assignment and the structure of C6H5C(OR)2+ were confirmed by a collision-induced dissociation experiment, where the dominant fragmention was found to be C6H5C(OH)2+. In comparison with the productions by the nanosecond and femtosecond lasers, it is concluded that C6H5CCl(OR)+ and C6H5C(OR)2+ are produced by the reaction of the ionic precursor, C 6H5CCl2+, with alcohol, ROH.
