The neutral OH molecule has been implicated in certain ozone-destroying processes which take place in the upper atmosphere.
a) Electron affinity can be defined for molecules just as it is defined for single atoms. Write a complete chemical equation representing the electron affinity of OH. Include all relevant state symbols ((s), (g), etc.)
b) Assuming that the electron added to OH is entirely localized in a single atomic orbital on one atom, identify which atom (O or H) is probably accepting the electron, and the n and l quantum numbers of the atomic orbital that is doing so.
c) The electron affinity of OH has been measured to be similar, but slightly more negative than the electron affinity of single O atoms. Explain briefly why the electron affinity is similar but slightly more negative.
