Molecular chemistry deals with the laws governing the interaction between molecules that results in the formation and breakage of chemical bonds, while molecular physics deals with the laws governing their structure and properties.
Molecular spectroscopy is the study of the response (spectrum) of a molecule to a signal characterized by its tunable frequency (or, according to Planck formula, its energy).
The molecular response can be the absorption of the signal (absorption spectroscopy), the emission of another signal (emission spectroscopy), its fragmentation or a change of its chemical nature.

 Tantalizing evidence for molecular condensation (May 2002) - News - PhysicsWeb
To establish that the condensate was indeed in a superposition, the researchers applied a second magnetic pulse to break the superposition and then immediately measured the number of atoms in the condensate.
They discovered that this number – a measure of the relative phase between the atomic and molecular states – varied sinusoidally as the time between the pulses was increased.
Carl Wieman, one of the JILA researchers and a recipient of the 2001 physics Nobel prize for his creation of atomic Bose-Einstein condensation, believes that further proof is not really necessary.
