A molecular vibration occurs when atoms in a molecule are in periodic motion while the molecule as a whole has constant translational and rotational motion the frequency of the periodic motion is known as a vibration frequency, and the typical frequencies of molecular vibrations range from less than 10 13 to approximately 10 14 hz. Ch2 is one carbon and two hydrogen it does not exist on its own but is often a part of larger molecules ch2 is one carbon and two hydrogen it does not exist on its own but is often a part of larger molecules.
