I'm thinking thermodynamics, but I'm not sure

We covered thermodynamics in our chemistry course

thermodynamics is part of physical chemistry. IR spectroscopy is a part of spectroscopic techniques in chemistry , important for the study of vibrations of bonds between atoms.

Infrared spectroscopy (IR Spectroscopy) is the subset of spectroscopy that deals with the IR region of the Electro magnetic spectrum. It covers a range of techniques, with the most common type by far being a form of absorption spectroscopy. As with all spectroscopic techniques, it can be used to identify a compound and to investigate the composition of a sample.
Spectroscopy is the study of the interaction between radiation (electromagnetic radiation, or light, as well as particle radiation) and matter. Spectrometry is the measurement of these interactions and a instrument which performs such measurements is a spectrometer or spectrograph. A plot of the interaction is referred to as a spectrogram, or, informally, a spectrum.

Thermodynamics is a part of physics, but not chemistry. Infrared is a wave form that is below our frequency range for vision. We usually detect it as heat. However, your clue is the word spectroscopy. Spectroscopy uses the interaction of light waves with a physical substance. In the case of infrared spectroscopy we are measuring the interaction between infrared light and a physical substance. This is often used in chemistry to identify one or more substances by its' (their) emitted spectrum. See wiki below.

Infra red measures the forces existing between two atoms. In a molecule two atoms are always vibrating .the energy of vibration is of the same order tan the energy of an infrared vibration. So if you consider two atoms being related by a spring between them, you can determine the energy of the spring

i'd say organic cos u usually use it to see what functional groups are present in ur compound, or if ur lazy whether it has dried or not, lol!
