- Abstract
- stretching excitation. It is faster than in alpha-hydroxyester or alcohol dimers but slower than in carboxylic acid dimers. For this purpose, supersonic jet FTIR and Raman spectra of free and Ar-nanocoated acetoxime monomers, dimers and trimers are presented. By comparison to heated nozzle cyclohexanone oxime spectra, to condensed phase data and to quantum chemical calculations, a Fermi resonance description of the O-H stretching dynamics in the symmetric, doubly hydrogen-bonded dimers is obtained. C=N stretching and librational O-H bending modes are predicted to participate in the coupling. Hydrogen bond topologies and cooperativity issues in larger oxime clusters are discussed.
