Abstract
Resonance-enhanced two-photon ionization time-of-flight spectroscopy has been applied in a supersonic beam to study R-(+)-1-phenyl-1-propanol (PR) and its diastereomeric clusters with R(–) and S(+) 2-butanol (BR; BS) and with R(–) and S(+) 2-butylamine (AR, AS). This mass resolved spectroscopy allowed us to assign a few vibronic frequencies of PR and measure the spectral shift of the diastereomeric clusters PRBR, PRBS, PRAR, and PRAS. The different bathocromic shifts observed in the two pairs indicates the possibility for spectroscopically differentiating the aggregates. Moreover, very reproducible differences in the fragmentation patterns provide an additional tool for their discrimination.
