The energy spectrum refers to the possible energy of a system.

The eigenvalues of H represents the possible energies that can be observed.

When considering energies, possible rotational energy before and/or after a collision may also play a role.

This gives your growing fetus a healthy start and gives you the most possible energy to use for parenting.

Property Section staff are committed to saving energy wherever possible:

The collection of all possible energies and momenta is known as the band structure of a material.

The goal is to bring the system, from an arbitrary initial state, to a state with the minimum possible energy.

It is used to calculate the maximum possible electrical energy that could be obtained from a chemical reaction.

Spend the least possible energy doing it If you can't manage it... tough.

The orbital has the lowest possible energy in the atom.
