Another example is a recent study of proton affinities of a furan, methylphenols and related anisoles by van Beelen et al. [87]. The proton affinities were determined by ion cyclotron resonance mass spectroscopy and theoretically by G3(MP2) theory. The G3(MP2) proton affinity provided support for revision of the proton affinity of furan... [Pg.808]

The MINDO/3 method has been applied to calculate the proton affinity (basicity) of all anisole positions and the change of bond lengths in passing from... [Pg.222]

Anisole (methylphenylether) can be regarded as methylated phenol and has been proposed (Kauppda 2004a) as a suitable dopant for APPI of analytes with low proton affinity (PA) values in reverse phase HPLC solvents in which benzene and toluene are unsuitable. Previously only acetone was used in these conditions but its fairly high PA (812kJ.mop ) meant that it was suitable for only analytes with even higher PA values. It was shown... [Pg.210]
