It might be instructive as an illustration to consider the uniform flow of a polyatomic gas past a blunt-nosed body over a wide range of speeds. For example, the excitation of rotational and vibrational modes of a polyatomic gas (without dissociation) can be represented by the equation of state of a thermally perfect gas. An example of a polyatomic ion is the hydroxide ion - consisting of one oxygen atom and one hydrogen atom, hydroxide has a charge of 1.
