The vibrational energy of a molecule is typically given in units of cm^(-1), which represents the energy difference between two vibrational states. In this case, the vibrational energy of molecule AX is given as 1000 cm^(-1).

This means that there is an energy difference of 1000 cm^(-1) between the two vibrational states of molecule AX. Vibrational energy levels are quantized, meaning they can only take on certain discrete values. The higher the energy level, the more vibrational energy the molecule possesses.

The vibrational energy of a molecule is determined by various factors, including the masses of the atoms involved, the strength of the chemical bonds, and the shape of the molecule. It is an important property to consider in many areas of chemistry, such as spectroscopy and chemical reactions.
