11. Vibronic spectra of diatomic molecules in the gas phase have been analyzed in detail. 12. A homonuclear diatomic molecule is one composed of two atoms of the same NO. 13. Other elements form diatomic molecules when evaporated, but these diatomic species repolymerize when cooled. 14. Asymmetrical diatomic molecules , e . g. 15. All of the elements in the period can form diatomic molecules except beryllium and neon. 16. "' Hydrogen bromide "'is the diatomic molecule with the formula. 17. All halogens have been observed as diatomic molecules , except for astatine, which is uncertain. 18. For example, molecular nitrogen is inert under ordinary conditions, existing as diatomic molecules ,. 19. Evidence has been obtained for the presence of the diatomic molecule TiO in the interstellar medium. 20. Heavy hydrogen gas would form near one electrode, and form into diatomic molecules , right?
