There are many other interpretations of quantum mechanics, but this is considered the most important - since quantum calculations can be understood.

In the quantum mechanical calculation of energy absorption, the represent Fermi-golden-rule transition rates between energy levels.

Force field functions and parameter sets are derived from both experimental work and high-level quantum mechanical calculations.

In many cases, large molecular systems can be modeled successfully while avoiding quantum mechanical calculations entirely.

The favoured conformation of this glycal is the half-chair, a result which has been confirmed by quantum mechanical calculations.

The quantum mechanical calculation incorporating these corrections (and some others) correctly predicted the multiple lines.

For example, a naive quantum mechanical calculation of the ground-state energy density yields infinity, which is unreasonable.

Numerical methods must be applied in order to obtain (approximate) wavefunctions or other properties from quantum mechanical calculations.

In other words, it says that for large orbits and for large energies, quantum calculations must agree with classical calculations.
