Quantum Chemistry is the application of quantum mechanics to solve problems in chemistry. It has been applied in different branches of chemistry
Physical Chemistry: To calculate thermodynamic properties, interpretation of molecular spectra and molecular properties (e.g. Bond length, bond angles, …..etc.).
Organic Chemistry: To estimate the relative stabilities of molecules, and reaction mechanism.
Analytical Chemistry: To Interpret of the frequency and intensity of line spectra.
Inorganic Chemistry: To predict and explain of the properties of transition metal complexes.

Historical background of quantum mechanics:Nature of light:
Hertz, 1888, has showed that light is electromagnetic waves. = c /
where, is the wavelength, c is the speed of light =2.998 x 1010 cm/sec, is the frequency cm/sec.Max Plank has assumed only certain quantities of light energy (E) could be emitted. E = hWhere, h is Plank’s constant = 6.6 x 10-27 erg.sec. The energy is quantized.
Photoelectric effect: Light comes out by shining surface in vacuum.In 1905, Einstein, light can exhibit particle like behavior, called photons.
Ephoton = hh = W + ½ mv2
where, W is the work function (minimum energy required to take electron out). ½ mv2 is the kinetic energy of emitted electron. From above, it is assumed that the
{Light looks like a particle and a wave}
Nature of Matter:
Rutherford and Geiger have found that some -particles bounced right back from golden foil, have small positive nucleus in atom.In 1913, Bohr has studied the H-atom and assumed that the energy of electron is quantized, = E / hwhere, is the frequency of absorbed or emitted light, E is the energy difference between two states.
In 1923, DeBroglie has suggested that the motion of electrons might have a wave aspect. = h / mv = h / pwhere, m is mass of electron. p is a particle momentum.Accordingly, it has been suggested that electrons behave in some respect like particles and in some others like waves. This is what is called a
Particle –Wave Duality.
The question arises, how can an electron be a particle, which is a localized entity, and a wave, which is nonlocalized?
The answer is No, neither a wave nor a particle but it is something else.The Classical physics has failed to describe the microscopic particles.
The question arises, how can an electron be a particle, which is a localized entity and a wave which is a non-localized?
The answer is No, neither a wave nor a particle but it is something else.
Heisenberg Uncertainty Principle:
"It is impossible to determine precisely and simultaneously the momentum and the position of an electron
The statistical definition for the uncertainties is:
x . px ħ / 2
where, = ħ / 2
x . px h / 4
Werner HeisenbergNobel prize 1932
To describe the state in quantum mechanics, we postulate the existence of a function of the
coordinates called the wave function (State function), .
= (x, t)
It contains all information about a system. The probability of finding a particle in a given place can be given by (Probability description).
Wave Function:
What (x) means?
- is an amplitude, sometimes complex function, not measurable, imaginary value.
- * is a complex function, which may be real, and positive.
- has no physical meaning but * is the probability of locating the electron at a
given position.
If the probability of a certainty is defined as unity, this means:
1)()( * zyxxx
If we have two different wave functions, 1 and 2 will be Normalized function when:
1)()( 1*
1 zyxxx and
1)()( 2*
2 xx
But if
0)()( 21 xx or
0)()( 2*
1* xx
The function is called orthogonal function.
But if
ijji xx )()(
Where, ij (called Kronecker Delta) is equal zero when i j and equal one when i = j, the
function is called orthonormalized function.
Time-dependent Schrödinger equation:
we postulate the existence of a function of the coordinates called the wave function (State function), . For one particle, one-dimensional system:
= (x, t)
It contains all information about a system. The probability of finding a particle in a
given place can be given by (Probability description).
Born postulates | (x,t) |2 dx is the probability of finding a particle at position x and
at time t ( Probability density ). must satisfy Schrödinger equation. As t passes, changes to differential equation:
where, i= , m = particle mass, V(x,t) = potential energy. This is called Time-dependent Schrödinger equation.

III- The Hydrogen atom:
Ignoring interatomic or intermolecular interactions, The isolated hydrogen atom is a two-particle system. Instead of treating just the hydrogen atom, we consider a slight more general problem, the hydrogen-like atom. An exact solution of the Schrödinger equation for atoms with more than one electron cannot be obtained because of the interelectronic repulsions.
V = -Z é 2 / r
Where, V is the potential energy, Zé is the charge of nucleus, (For Z=1, we have the hydrogen atom, for Z=2 the He+ ion, for Z=3, the Li+ ion, etc…).é is the proton charge in statocoulombs or as:

where, e is the proton charge in coulomb. To deal with the internal motion of the system, we introduce as the mass of the particle. = me mn / me + mn
where, me and mn are the electronic and nuclear masses.

Molecular Orbital Theory:
The MO Theory has five basic rules: 1-The number of molecular orbitals = the number of atomic orbitals combined of the two MO's, one is a bonding orbital (lower energy) and one is an anti-bonding orbital (higher energy) 2-Electrons enter the lowest orbital available 3-The maximum # of electrons in an orbital is 2 (Pauli Exclusion Principle) 4- Electrons spread out before pairing up (Hund's Rule)
