Complete active space self-consistent calculations of the energy and dipole moment functions were carried out for C3 in its electronic ground state. The absorption coefficient between 0.7 and 75 microns is calculated on the basis of the vibrational band strength of transitions between the 800 lowest states with v less than or equal to (4, 39, 3). In cool carbon stars with a high C/O ratio, C3 is found to be the most prevalent of the known opacity sources. 49 refs.
