A linear combination of atomic orbitals or LCAO is a quantum superposition of atomic orbitals and a technique for calculating molecular orbitals in quantum chemistry. In quantum mechanics, electron configurations of atoms are described as wavefunctions. In a mathematical sense, these wave functions are the basis set of functions, the basis functions, which describe the electrons of a given atom. In chemical reactions, orbital wavefunctions are modified, i.e. the electron cloud shape is changed, according to the type of atoms participating in the chemical bond. It was introduced in 1929 by Sir John Lennard-Jones with the description of bonding in the diatomic molecules of the first main row of the periodic table, but had been used earlier by Linus Pauling for H2+. (Wikipedia).
Definition of Linear Combination and How to Show a Vector is a Linear Combination of Other Vectors
Definition of Linear Combination and How to Show a Vector is a Linear Combination of Other Vectors More Linear Algebra! This starts with the definition of a Linear Combination and then we show a Vector in R^3 is a linear combination of other vectors in R^3. Solid example. I hope this help
