“vibrational level”造句，怎麼用vibrational level造句

The rotational levels of the ground vibrational level may be depopulated by radiation.

Such photons will excite the higher vibrational levels of the OH molecule.

Effect on vibrational levels of H_2~+ by its approximate analytic wave function for the ground state

So molecules might generally still be in the ground vibrational levels, thermal energy isn't enough to raise them in many cases.
