Pauling & E. B. Wilson Introd. Quantum Mech. vii. 182 The variation method is..very frequently used to obtain approximate wave functions as well as approximate energy values. 1960 McGraw-Hill Encycl. Sci. & Technol. XI. 145/2 The most useful of these methods, the variation method, has produced most of the important quantum-chemical concepts. 1974 P. W. Atkins Quanta 96/2 With these approximations in hand the variation method is applied to determine the best linear combination of atomic π-orbitals to describe the structure of the molecule. < as lemmas |
