Spectroscopy involves the study of the interaction between matter and electromagnetic radiation. In the case of 2-butanone, also known as methyl ethyl ketone (MEK), several types of spectroscopy can be applied to gather information about its molecular structure and composition. The specific spectral data you would expect for 2-butanone include:

1. Infrared Spectroscopy (IR):
   - Functional Groups: IR spectroscopy can identify functional groups within a molecule. For 2-butanone, you would expect to see peaks corresponding to the carbonyl group (C=O) around 1700 cm⁻¹.
   - Other Functional Groups: IR can also provide information about other functional groups, such as C-H stretching and bending vibrations.

2. Nuclear Magnetic Resonance (NMR) Spectroscopy:
