Laser-induced fluorescence spectroscopy and structure of microsolvated molecular clusters. Part 3.—Methyl and ethyl 4-amino- and 4-pyrrolidino-benzoates, and 4-amino-and 4-pyrrolidino-benzonitrile with Ar, Kr, CH4, H2O or CH3OH

1992 
An iterative band contour simulation strategy has been extended to the analysis of partially resolved rovibronic bands in the laser-induced fluorescence (LIF) spectra of complexes of jet-cooled, substituted aromatic amines (4-aminobenzonitrile, ethyl 4-aminobenzoate, methyl 4-aminobenzoate, 4-pyrrolidinobenzonitrile, ethyl 4-pyrrolidinobenzoate and methyl 4-pyrrolidinobenzoate) with both polar and non-polar solvents. The pattern which emerges on complexation with non-polar solvents is of a high degree of site selectivity. With polar solvents several distinct conformers are observed, with different solvent shifts, for the same complex stoichiometry.
