Monosolvation effects in chiral fluoroorganic compounds: an R2PI study

Wavelength- and mass-selected resonant-enhanced two-photon ionization (R2PI) spectra of supersonically expanded (R)-1-phenyl-2,2,2-trifluoroethanol (FE(R)) and its complexes with water, R- and S-2-aminobutane (A(R/S)) and R- and S-2-butanol (B(R/S)) are reported and discussed in the light of ab initio calculations. The effects of the fluorine atoms in these systems have been evaluated by comparing the results with the vibronic and mass spectra of their nonfluorinated analogues, i.e. adducts with (R)-phenyl-1-ethanol (E(R)).
