The molecules exists as a colorless liquid at room temperature.
MO diagrams can explain why some molecules exist and others do not.
The patterns of wavelengths then tell us which atoms and molecules exist out there.
The strong suggestion is that the molecule exists primarily as a food source.
The molecules discussed thus far only exist diluted in the gas phase.
The molecule also exists as three singlet states with slightly higher energy.
If atoms didn't stay put fairly well, molecules would not exist.
Moreover, the temperature is so high that no molecules can exist, and most of the atoms are ionized.
Such mirror-image molecules exist, but the life forms we are familiar with don't use them.
The molecule can only exist in an excited state.
