Photochemical R2PI study of chirality and intermolecular forces in supersonic beam
One and two-color, mass selected R2PI spectra of the S1←S0 transitions in the bare (+)-(R)- 1-phenyl-1-ethanol (ER) and its complexes with different solvent molecules (solv) (-)-(R)-2-butanol (BR) or (+)-(S)-2-butanol (BS), (—)-(R)-2-pentanol (TR) or (+)-(S)-2-pentanol ( TS) and (-)-(R)-2-butylamine...

| description | One and two-color, mass selected R2PI spectra of the S1←S0 transitions in the bare (+)-(R)-
1-phenyl-1-ethanol (ER) and its complexes with different solvent molecules (solv) (-)-(R)-2-butanol (BR)
or (+)-(S)-2-butanol (BS), (—)-(R)-2-pentanol (TR) or (+)-(S)-2-pentanol (
TS) and (-)-(R)-2-butylamine (AR) or
(+)-(S)-2-butylamine (AS), have been recorded after a supersonic molecular beam expansion. The one-color
R2PI excitation spectra of the diastereomeric complexes are characterized by significant shifts of their band
origin relative to that of bare ER. The extent and the direction of these spectral shifts are found to depend
upon the structure and the configuration of solv and are attributed to different short-range interactions in
the ground and excited states of the complexes. In analogy with other diastereomeric complexes, the phenomenological
binding energy of the homochiral cluster is found to be greater than that of the heterochiral
one. Preliminary measurements of excitation spectrum of (+)-(R)-1-Indanol (IR) is also reported. |
