10 Questions
Infrared radiation is the electromagnetic radiation that lies between the visible and ________ regions of electromagnetic radiation.
microwave
The absorption of infrared radiation by a molecule occurs due to quantised vibrational and rotational energy changes when it is subjected to infrared irradiation. Thus, IR spectra are often called ________ spectra.
vibrational-rotational
Infrared (IR) spectroscopy is an analytical technique used to determine the bonds and functional groups in the structure of chemical compounds. The advantage of this technique is that any sample in virtually any state can be studied. For example, powder, paste, a mixture, gas films, and ________ can be easily examined.
fibres
The infrared spectrum can be divided into three types of main regions: 1. Far infrared, 2. Mid-infrared, and 3. ________ infrared.
near
Infrared spectroscopy is commonly used in chemical analysis due to its ability to provide information about the bonds and functional groups present in a molecule through the study of its ________ spectrum.
infrared
Infrared radiation has a longer wavelength than UV rays and longer frequencies than ________ light.
visible

Infrared Spectroscopy
- It is an analytical technique used to determine bonds and functional groups in chemical compounds' structures.
- Any sample in virtually any state can be studied, including powders, pastes, mixtures, gas films, and fibers.
Infrared Spectrum
- Divided into three main regions: far infrared, mid-infrared, and near infrared.
- IR spectra are often called vibrational-rotational spectra due to absorption of infrared radiation by molecules.
Absorption of Infrared Radiation
- Occurs due to quantized vibrational and rotational energy changes in molecules when subjected to infrared irradiation.
Learn about the fundamentals of infrared spectroscopy, which involves the absorption of infrared radiation by molecules leading to vibrational and rotational energy changes. Explore how IR spectra are referred to as vibrational-rotational spectra.
