✦ Synopsis

The first excited vibrational level of the n 3 mode (Ca-C stretch) and the n 3 / n 5 (Ca-C-C bending) combination level in the CaCCH X ˜2S / state have been rotationally analyzed. Data were obtained by dispersion of laser-induced fluorescence. The fundamental Ca-C stretch frequency was determined to be n 3 Å 397.400(2) cm 01 . The value of the l-type doubling constant, q v Å 00.2677 (21) 1 10 03 cm 01 , for the n 3 / n 5 level is very close to that determined previously for the n 5 level.

Using a Fourier transform spectrometer, we have recorded the spectra of ozone in the region of 4600 cm 01 , with a resolution of 0.008 cm 01 . The strongest absorption in this region is due to the n 1 / n 2 / 3n 3 band which is in Coriolis interaction with the n 2 / 4n 3 band. We have been able to a
