The electromagnetic spectrum encompasses all types of electromagnetic radiation, ranging from gamma rays with the shortest wavelengths to radio waves with the longest wavelengths. In organic chemistry, it plays a crucial role in structure determination by providing information about molecular vibrations and ion fragmentation patterns.
Imagine the electromagnetic spectrum as a grand piano keyboard. Each key represents a different type of electromagnetic radiation, from the high-pitched gamma rays on the left end (short wavelength) to the low-pitched radio waves on the right end (long wavelength). Just as each note on a piano can create different sounds, each type of radiation in the electromagnetic spectrum has unique properties used in spectroscopy to "hear" the structure of molecules.
Infrared Spectroscopy: A technique that measures how molecules absorb infrared light, revealing details about their chemical bonds and molecular structures.
Mass Spectrometry: An analytical method that ionizes chemical species and sorts the ions based on their mass-to-charge ratio, used for determining molecular weights and structures.
Wavelength: The distance between successive crests of a wave, which determines its energy and type within the electromagnetic spectrum
