Question
This is the third word of a method that uses character tables to identify equivalent atoms and stretching modes, where this word follows "symmetry adapted." This is the first word of a technique that uses the Hartree-Fock method to compute coefficients for the sum of a basis set of Gaussian or Slater-type orbitals. Molecular orbitals can be formed by a (*) combination of atomic orbitals described by this word. Molecules described by this six-letter word have 3N minus 5 vibrational degrees of freedom. Since it has three lone pairs and two bonds, tri·iodide has this molecular geometry. Carbon dioxide also has this geometry. For 10 points, name this geometry of molecules with a 180 degree bond angle. ■END■
ANSWER: linear [accept symmetry adapted linear combinations or linear rotors or linear combination of atomic orbitals]
