Experimental Values

Laser-induced fluorescence excitation spectra of five vibronic bands of 1-hexoxy and three bands of 1-heptoxy have been recorded in a jet-cooled environment. Experimental values of rotational constants for both the [Formula: see text] and [Formula: see text] states and components of the spin-rotational tensor for the [Formula: see text] state were obtained by an analysis of the partially resolved rotational structure of the vibronic bands. Comparing these experimental results with quantum chemistry calculations, and using corresponding assignments of smaller alkoxy radicals as a guide, permitted unambiguous conformational assignments for the bands. The extension of similar assignments to larger alkoxy radicals is also discussed. Key words: electronic spectroscopy, organic radicals, combustion, atmospheric chemistry.

Intramolecular Motions

The S1-S0 fluorescence excitation spectra of 5-chlorotropolone-M1 (M = Kr, Xe, CH4) van der Waals (vdW) complexes in the region near the electronic origin have been measured in a supersonic free jet to investigate the effect of the vdW interactions on proton tunneling. Tunneling splittings have been observed in the vdW vibrations as well as in the 000 transitions of the Kr and Xe complexes. The 000 tunneling splitting of the 5-chlorotropolone-(CH4)1 complex is significantly smaller than those of the Kr and Xe complexes. It has been suggested that the vdW vibrations couple with intramolecular motions, leading to a higher potential energy barrier to tunneling in the CH4 complex. The results of the 5- chlorotropolone complexes have been compared to those of the tropolone complexes.
