Is this a correct definition of spectroscopy?

spectroscopy is the study of how molecules behave when they interact with energy. spectroscopy involves bombarding a substance, whose chemical structure is unknown, with energy, and seeing which frequencies are absorbed. Because different functional and structural absorbs energies at specific frequencies, it is possible to determine the chemical structure of the substance.


I understand IR, HNMR, etc., I just want to make sure this definition is correct.

No offense, but this seems like a useless thread. (I really am curious why you posted it.) Watch this:

Spectroscopy is the study of matter and its properties by investigating light, sound, or particles that are emitted, absorbed or scattered by the matter under investigation.

Spectroscopy may also be defined as the study of the interaction between light and matter. Historically, spectroscopy referred to a branch of science in which visible light was used for theoretical studies on the structure of matter and for qualitative and quantitative analyses. Recently, however, the definition has broadened as new techniques have been developed that utilize not only visible light, but many other forms of electromagnetic and non-electromagnetic radiation: microwaves, radiowaves, x-rays, electrons, phonons (sound waves) and others. Impedance spectroscopy is a study of frequency response in alternating current.

spectroscopy [(spek-tros-kuh-pee)]

The branch of science devoted to discovering the chemical composition of materials by looking at the light (and other kinds of electromagnetic radiation) they emit. Scientists use spectroscopy to determine the nature of distant stars and galaxies as well as to identify and monitor the production of products in factories.

I doubt the DAT would test your knowledge of vocabulary words. If this is just reassuring yourself that you know what you're studying, you should just look around online or at your study guides. They're probably better than asking on these forums.

No offense taken. I always do research before posting on SDN, and I have already been to those links prior to posting this thread. You're correct, its just reassurance that I'm understanding everything as I read it. I understand the applications of spectroscopy very well, but I never learned the definitions and theory behind it. Your statement that this thread is "useless" is a subjective one: while it may seem useless to yourself, that does not necessarily mean it hold no value to me. If everyone has that mentallity, then this forum wouldn't exist.

Yes okay. I just remember seeing you do this many times and you usually have your info right, so it surprises me that you'd have to post a confirmation thread so often.

You're correct: I tend to post a lot of "confirmation threads." I study best when I put things in my own words, and I am always second-guessing myself. It's an anal characteristic that I tend to have. 😛
