Carbon dioxide laser saturation spectroscopy and the hyperfine structure of monosubstituted ozone 16O16O17O and 16O17O16O

Carbon dioxide lasers have been used in an offset-lock configuration to obtain saturation spectra of ozone, monosubstituted with O-17, at a linewidth of a few kHz. Rich hyperfine structures result from the O-17 nucleus, spin 5/2. These are used, together with earlier microwave data,to obtain the corresponding hyperfine parameters. The spectra also illustrate the sensitivity of hyperfine structures to subtle vibration-rotation interactions. (C) 1998 Academic Press.
