The spectral lines arising from the transitions between the octet S72 ground state and the sextet P72 32100cm and sextet P52 32700cm manifolds of Gd3 in CaF2 at 77K are grouped according to the sites to which they belong. The classification is based on the relative line strengths or integrated absorption coefficients by which lines can be grouped according to common sites, but does not yield the symmetries of these sites. The effects of the Gd3 within the sample on the relative strengths of the identified sites are reported for the nominal dopings of 0.5, 0.1, and 0.05 mole per cent. The integrated absorption coefficients, wavelengths in air, and vacuum wavenumbers of the sextet P72 and sextet P52 groups are reported. Wavelengths in air and vacuum wavenumbers of the sextet I group in absorption and the sextet P72 and sextet I72 in fluorescence are also included. Author
