✦ Synopsis

Laser induced fluorescence of a fast ion beam has been applied to 13 CO / 2 for its (0, 0, 0) A ˜2P u -(0, 0, 0) X ˜2P g UV electronic transition. The high resolution (0.005 cm 01 ) of the FIBLAS method, due to a highly reduced Doppler broadening, allows us to evaluate the isotopic shift, to appreciate the contribution of the central atom when determining molecular parameters, and, for the first time, to determine the influence of the central atom on hyperfine structure. Absolute calibration of the 13 CO / 2 spectra is obtained by means of a 12 CO / 2 -13 CO / 2 spectrum, allowing calibration via FT spectra of 12 CO / 2 .
