Notes.

^(†)

Since the ortho and para spin isomer variants of both water and ammonia behave as different chemical species, for all ortho transition E_upp/k values are relative to the corresponding lowest ortho energy level, while for the para transitions they are given w.r.t. the corresponding lowest para energy level.
