| 1. | The bond in a homonuclear diatomic molecule is non-polar.
|
| 2. | This is typical of the infrared spectra of heteronuclear diatomic molecules.
|
| 3. | Simple diatomic molecules have only one bond and only one vibrational band.
|
| 4. | Will this never happen for single-bonded diatomic molecules?
|
| 5. | In symmetrical homonuclear diatomic molecules, the permanent electric dipole moment vanishes.
|
| 6. | Diatomic molecules consist of a bond between only two atoms.
|
| 7. | In diatomic molecules, the number of vibrational degrees of freedom is 1.
|
| 8. | In the vapour phase, beryllium oxide is present as discrete diatomic molecules.
|
| 9. | A diatomic molecule has one normal mode of vibration.
|
| 10. | Single bonds are often seen in diatomic molecules.
